Intelligent resource allocation framework for dynamic allocation of system resources in personal computing device (PCD) employing wireless modem

Abstract

Systems, methods, and computer readable media may be used in a portable computing device (PCD) to dynamically allocate system resources in a manner that prevents or reduces degradation of power and performance KPIs while also avoiding temperature increases in the PCD that may create an unpleasant user experience. When a call is received or issued, an intelligent resource allocation framework (SRAF) is triggered. Once triggered, the SRAF framework monitors a preselected set of state conditions to determine whether to place the wireless modem in a modem power performance (Mod. Pow.-Perf.) mode. If it is determined that the modem is to be placed in the Mod.Pow.-Perf. Mode, a Mod.Pow.-Perf. Process is performed that dynamically allocates system resources and preferably also triggers a thermal framework that performs power reduction in one or more non-modem processing cores.

Description

[0001] Related technical description

[0002] Wireless devices use wireless modems to directly connect to and communicate with wireless networks. Most portable computing devices (PCDs) such as mobile phones, tablet portable computers (i.e., iPads), laptop computers, smart wearable devices, and Internet of Things (IoT) devices use wireless modems. When not charged, PCDs all run on batteries. In such devices, if system resources are not properly and efficiently utilized, serious degradation of key performance indicators (KPIs) for power and performance may occur. This is especially true for currently available and upcoming PCDs that incorporate newer wireless modem features for higher bandwidth (BW) wireless communication protocols (e.g., fourth generation (4G), long term evolution (LTE), fifth generation (5G), 5G new radio (NR), sixth generation (6G), etc.).

[0003] There is typically no intelligent framework for proactively allocating system resources in a PCD in a manner that ensures that performance and power KPIs are not degraded. Some PCDs implement a use case thermal framework that 1) uses the output of one or more temperature sensors to detect when a long duration call has caused the temperature of the PCD to rise to the point where the user senses heat from the PCD, and then 2) disables modem features to reduce power usage until the temperature slowly decreases to the point where the user no longer senses heat. One disadvantage of this type of thermal framework is that disabling modem specific features to reduce power usage, thereby reducing temperature, degrades modem performance. Another disadvantage is that the thermal framework is not proactive in that it is only triggered after the user senses heat during a call, i.e., it does not proactively mitigate temperature increases before the user senses heat. Additionally, this type of thermal framework is only triggered during the use case of long duration calls.

[0004] Some PCDs dynamically allocate system resources in an attempt to prevent degradation of power and performance KPIs, but such allocation schemes are only partially effective. In recently developed system-on-chip (SoC) technology used in PCDs, last level caches (LLCs) have been introduced to improve system performance and reduce usage power usage and impact. LLC allocation is currently performed in two ways: "static reservation" allocation and "free pool for opportunity" allocation. Each system "client" is assigned a priority and a maximum storage capacity of the LLC in kilobytes (KB), and may or may not be assigned a reserved area in the LLC. This allocation is performed on a one-time basis using a system cache table defined in the kernel code of the PCD operating system (OS).

[0005] As shown in the following example, there are disadvantages to this type of resource allocation scheme. Assuming a relatively simple system in which the PCD's central processing unit (CPU) and modem are the only clients accessing the system LLC, and assuming the LLC size is 4 megabytes (MB), with 3MB reserved for the CPU and 1MB reserved for the modem, even if the CPU does not fully utilize its 3MB of reserved LLC, the modem will not be allocated more than 1MB of LLC (even if it is very eager for the system cache). Such scenarios are very common when the user is performing a voice call or a data call and reveal that the system cache is a very important resource that is not being properly and extensively utilized. In such scenarios, long duration NR / LTE calls result in more radio frequency (RF) dissipation, which results in heat accumulation near the user's ears, which creates an unpleasant user experience. As indicated above, the current thermal framework solution to this problem is to disable modem specific features to reduce power usage and therefore reduce temperature, which results in the aforementioned disadvantages.

[0006] What is needed is a system and method for use in a PCD with a wireless modem for more efficiently, proactively, and dynamically allocating system resources in a manner that prevents or reduces degradation of power and performance KPIs while also avoiding temperature increases in the PCD that can create an unpleasant experience for the user.

DETAILED DESCRIPTION

[0019] The present disclosure discloses a system, method, and computer-readable medium for use in a PCD with a wireless modem for more efficiently, proactively, and dynamically allocating system resources in a manner that prevents or reduces degradation of power and performance KPIs while also avoiding temperature increases in the PCD that can create an unpleasant experience for the user. These systems, methods, and computer-readable media provide a Smart Resource Allocation Framework (SRAF) that is triggered when a call is received or placed.

[0020] Once triggered, the SRAF framework monitors preselected criteria to determine whether to perform a modem power performance (Mod. Pow. -Perf.) procedure. If it is determined that the Mod. Pow. -Perf. procedure is to be performed, it performs one or more and preferably all of the following: (1) it dynamically updates the modem system cache table entries to, for example, increase the size of cache memory allocated to the modem, change the rank of the modem for accessing the cache memory, assign a high priority classification to the modem for accessing the cache memory, change one or more policies related to the modem accessing the cache memory, allocate cache to the modem from some other subsystem pool, etc.; (2) it actively triggers the thermal framework of the PCD to cause it to perform power reduction in one or more non-modem processing cores (e.g., power reduction in one or more CPUs, GPUs, CDSP cores, etc.) to reduce the temperature of the PCD before the user senses heat; and (3) it monitors feedback received from one or more intellectual property (IP) blocks of the PCD regarding the actual bandwidth required by the IP blocks, and dynamically allocates bandwidth in excess of the actual bandwidth required to a free pool accessible to the wireless modem for use by the wireless modem to improve its performance.

[0025] It will be understood that when an element is described as being “connected to” or “coupled to” or “electrically coupled to” another element, the elements may be directly connected or coupled or intervening elements may be present.

[0026] The term "memory" or "memory device" as used herein is intended to mean a non-transitory computer-readable storage medium capable of storing computer instructions or computer code for execution by one or more processors. References to "memory" or "memory device" herein should be interpreted as one or more memories or multiple memory devices.

[0028] A computing device may include multiple subsystems, cores, or other components. Such a computing device may be, for example, a portable computing device (“PCD”) with a wireless modem, such as a mobile phone, a tablet portable computer (e.g., iPad), a laptop computer, a smart wearable device, and an Internet of Things (IoT) device, a smart phone, a portable digital assistant (PDA), a portable game console (e.g., an extended reality (XR) device, a virtual reality (VR) device, an augmented reality (AR) device, or a mixed reality (MR) device), etc.

[0029] Multiple subsystems, cores, or other components of a computing device may be included within the same integrated circuit chip or in different chips. A SoC is an example of a chip that integrates numerous components to provide system-level functionality. For example, a SoC may include one or more types of processors, such as a central processing unit ("CPU"), a graphics processing unit ("GPU"), a digital signal processor ("DSP"), and a neural processing unit ("NPU"). The SoC may include other processing subsystems, such as a transceiver or "modem" subsystem that provides wireless connectivity. The components of the SoC (such as, for example, a GPU, DSP, NPU, video processor, wireless local area network (WLAN) processor, modem, and other components) are typically implemented on the SoC in logic blocks commonly referred to as intellectual property (IP) blocks. As the term is used herein, the term "IP block" is intended to represent an IP block of a SoC for a case in which a PCD employs a SoC, as well as a combinational logic block employed for similar purposes in an IC of a PCD that is not necessarily a SoC.

[0030] The PCD may include resources shared between one or more SoC processors, processing cores, or other SoC processing subsystems. For example, the processors may share access to the main memory or system memory and cache memory of the PCD. For example, the processors may also be associated with local cache memory (such as LLC).

[0031] Figure 1 1 is a flow chart of an SRAF process according to a representative embodiment. The SRAF process includes: a first process portion that monitors preselected criteria to determine whether a Mod.Pow.-Perf. process should be initiated; and a second portion that includes the Mod.Pow.-Perf. process. At the step represented by box 101, a determination is made as to whether the PCD has received or placed a call. If so, the first portion of the SRAF process monitors a preselected set of status conditions of the PCD to determine whether the monitored set of preselected status conditions indicates that the modem should be placed in Mod.Pow.-Perf. mode, wherein the Mod.Pow.-Perf. process is performed, as indicated by box 102. Reference is made below to Figure 2A A set of pre-selected status conditions that may be monitored are described in greater detail.

[0032] If it is determined at block 102 that the set of preselected status conditions monitored indicates that the wireless modem should be placed in Mod.Pow.-Perf. mode, then the second portion of the SRAF process is performed, which includes Figure 1The Mod.Pow.-Perf. process represented by blocks 103, 104, and 105 in the PCD. The process represented by block 103 includes dynamically updating one or more cache table entries associated with a modem of the PCD. The process represented by block 104 includes triggering a thermal framework process of the PCD that reduces power usage in one or more non-radio modem processing cores to reduce the temperature of the PCD. The process represented by block 105 includes monitoring feedback from one or more IP blocks of the PCD regarding actual bandwidth required by the blocks, and dynamically allocating bandwidth in excess of the actual bandwidth required to a free pool accessible to the radio modem for use by the radio modem to improve its performance. The following references Figure 2B The process represented by blocks 103 - 105 is described in more detail.

[0033] Figure 2A is a flow chart of a first portion of the SRAF process according to a representative embodiment, which, as described above, determines whether the monitored preselected status conditions indicate that the Mod.Pow.-Perf. process should be initiated, and if so, initiates and executes the Mod.Pow.-Perf. process. The Mod.Pow.-Perf. process is described below with reference to Figure 2B Give a description.

[0034] refer to Figure 2A , block 201 depicts that when a PCD user places a call or accepts a call with a PCD, the SRAF process is triggered or initiated. For example, a caller / receiver event handler or a modem stack event handler may detect when an incoming call is received or an outgoing call is placed and cause the SRAF process of the present disclosure to execute. Once this occurs, the next series of steps represented by blocks 202-205 are executed by the SRAF process to determine whether the Mod.Pow.-Perf. process of the SRAF process will be triggered or initiated.

[0035] According to a representative embodiment, the set of preselected status conditions monitored include: for example, a status condition indicating that the display screen of the PCD is locked, a status condition indicating that the display screen is turned off, a status condition indicating that the proximity sensor has sensed that the PCD is close to the user's ear, a status condition indicating that the light sensor has detected that the PCD is in the user's pocket or handbag, and a status condition indicating that the user is speaking via a Bluetooth headset paired with the PCD.

[0036] Detection of one or more of these status conditions indicates that performing the Mod. Pow. -Perf. process will likely not adversely affect the visible performance of the PCD. If one or more of these status conditions are detected, the process moves to block 205, which will be described in more detail below. If one or more of these status conditions are not detected, the process exits or returns to block 201. Also, if the call is terminated at any time after the SRAF process is triggered at block 201, the SRAF process terminates and / or returns to block 201.

[0037] According to a representative embodiment, the set of preselected status conditions monitored may also include status conditions related to a caller history or caller ID history associated with a party to whom a call is placed or from whom a call is received, as indicated by block 203. The historical data may be analyzed to determine whether modem performance needs to be improved or may require improvements to a current call that is occurring. The historical data may be analyzed to determine, for example, call conditions that have historically occurred in the current geographic location (Geo location) of the PCD (e.g., more voice failures, less network capacity coverage, latency ping-pong, a large number of network drops in a geographic location / region). The historical information may also include a caller or caller ID history that may be analyzed to determine, for example, whether calls with another party participating in the call are typically of long duration and / or occur frequently, thereby indicating that the call is important and may require modem performance improvements and / or may require triggering of a thermal framework, or involve large amounts of data transfer for business or work-related calls, etc. that indicate that modem performance improvements may be required. The caller ID and caller history data may also include, for example, whether the other party participating in the call is in a speed dial list, a contact list, a favorite contact list, is a contact that has been marked as important, is a contact that contains a keyword (such as, for example, "mom", "dad", "sister", "brother", "family member", etc.) It should be noted that caller or caller ID history data other than those discussed above with reference to box 203 can be monitored to determine whether there are more status conditions that indicate that the Mod. Pow.-Perf. process should be initiated.

[0038] If the monitored status conditions associated with the caller or caller ID history data indicate that improved modem performance is currently needed or will likely be needed for the current call, then the process moves to block 205. Otherwise, the process exits or returns to block 201. Also, as indicated above, if the call is terminated at any time after the SRAF process is triggered at block 201, then the SRAF process terminates and / or returns to block 201.

[0039] According to a representative embodiment, the pre-selected set of status conditions may also include whether an original equipment manufacturer (OEM) setting in the PCD or a user setting in the PCD indicates that the Mod.Pow.-Perf. process should be initiated for a particular type of call (whenever the SRAF process is initiated). For example, the particular type of call may be a call for which a high priority is assigned to the modem in order to ensure that the modem exhibits high performance, such as, for example, a data call or a video call. If yes, the process moves to block 205. If no, the process exits or returns to block 201.

[0040] It should be noted that status conditions of the PCD other than the example given above with reference to blocks 202 through 204 may be monitored to determine whether the Mod. Pow.-Perf. process should be initiated.

[0041] According to a representative embodiment, the processes represented by blocks 202 to 204 are performed in parallel, but they may be performed serially or partially in parallel and partially in serial. With respect to blocks 202 and 203, whenever the SRAF process is initiated at block 201 to perform the monitoring tasks of blocks 202 and 203, computer codes including a status status notifier and a caller / caller ID notifier may be initiated, respectively.

[0042] If the answer to any of the questions posed in blocks 202 through 204 is affirmative, the process moves to block 205 where it is determined whether triggering the Mod.Pow.-Perf. process under the current conditions of the current call will degrade the visible performance of the PCD, as indicated by block 205. If it is determined at block 205 that triggering the Mod.Pow.-Perf. process under the current conditions of the current call will not degrade the visible performance of the PCD, the process proceeds to Figure 2B The Mod.Pow.-Perf. process is triggered at block 206. Preferably, even after the Mod.Pow.-Perf. process is triggered at block 206, if the call is terminated, the SRAF process is terminated and the process returns to block 201.

[0043] When the Mod.Pow.-Perf. process is initiated, the SRAF process proceeds to the process represented by block 207. Block 207 includes Figure 1The process represented by boxes 103, 104 and 105. In block 207, the Mod.Pow.-Perf. process performs steps including at least one of, and preferably all of, the following: (1) dynamically updating a modem system cache table entry to indicate that modem performance is to be improved by setting a cache table entry (setting a cache table entry to, for example, indicate that the size of cache memory allocated to the modem will be increased, the rank of the modem for accessing the cache memory will be changed, the modem will be assigned a high priority classification for accessing the cache memory, a change will be made to one or more policies related to modems accessing the cache memory, cache from some other subsystem pool will be allocated to the modem), as indicated in block 103; (2) actively triggering a thermal framework of the PCD to cause the thermal framework to perform power reduction in one or more non-modem processing cores (e.g., power reduction in one or more CPUs, GPUs, CDSP cores, etc.), as indicated in block 104; and (3) monitoring feedback from one or more IP blocks of the PCD regarding actual bandwidth required by the IP blocks, and dynamically allocating bandwidth in excess of the actual bandwidth required to a free pool accessible to the wireless modem for use by the wireless modem to improve its performance, as indicated in block 105.

[0044] As indicated above, a known thermal framework in some PCDs disables modem features to reduce power usage, thereby reducing the temperature of the PCD until the user no longer senses heat. One disadvantage of the known thermal framework is that it is not proactive, as it only reduces temperature after the user has already sensed heat during a long-duration call. In other words, this type of thermal framework does not proactively mitigate temperature increases before the user senses heat. Additionally, the known thermal framework is only employed during the use case of long-duration calls. In contrast, the process represented by block 104 proactively triggers the thermal framework of the present disclosure to reduce power usage of the non-modem core so that modem performance is not adversely affected.

[0045] Thus, according to representative embodiments of the present disclosure, modem performance is improved by dynamically updating cache table entries while concurrently reducing power usage in the non-modem core of the PCD to reduce the temperature of the PCD before heat is sensed by a user.

[0046] With respect to dynamically allocating BW usage for one or more IP blocks of the SoC based at least in part on feedback from the IP blocks regarding actual BW required under current conditions for current calls, this can be performed by monitoring feedback received from each IP block or IP block subsystem and determining their actual required BW over a preselected time period. Any BW in excess of the actually required BW can be allocated to a free pool that the wireless modem can access and use to improve its performance.

[0047] The disclosed system and method for providing SRAF may be implemented in a PCD, although the inventive principles and concepts are not limited in the type of device implementing the method.

SRAF management circuitry 310 may also be implemented partially or entirely within CPU 304 rather than in a separate circuit.

[0050] The PCD 300 may include a display controller 309 and a touch screen controller 312 coupled to the CPU 304. A touch screen display 314 external to the SoC 302 may be coupled to the display controller 309 and the touch screen controller 312. The PCD 300 may also include a video decoder 316 coupled to the CPU 304. A video amplifier 318 may be coupled to the video decoder 316 and the touch screen display 314.

[0055] Reference again Figure 2A and Figure 2B If the call is Figure 2A and Figure 2B 101. If the SRAF process depicted in FIG. 10 is terminated at any time during the SRAF process, the cache table entries changed at block 103 / 207 are preferably restored to their previous values, i.e., the values ​​before the call was connected at block 201.
