Secondary Processor Firmware Dynamic Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer systems with secondary processors (SPs) face challenges in dynamically configuring clock frequencies and parameters at runtime, leading to potential system hangs or crashes due to hardcoded firmware requirements and limited configurability, especially when multiple SPs operate at different frequencies.
Innovation Solution
A method where a host processor modifies parameters stored in predetermined addresses within the SP memory, allowing for dynamic reconfiguration of clock frequencies and other settings without recompiling the firmware, enabling SPs to operate with different parameter values from a single binary file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If firmware is compiled with hardcoded clock frequency parameters, then the firmware can be efficiently executed by secondary processors, but the system cannot dynamically adjust clock frequencies at runtime without recompiling the firmware
Solution Approach 1:
The patent segments the firmware into two distinct parts: compile-time configuration data (stored in metadata or header sections) and runtime executable code. This allows the executable code to remain fixed and efficiently compiled, while the configuration data can be dynamically modified at runtime without requiring recompilation of the entire firmware binary.
Solution Approach 2:
The patent performs preliminary configuration by embedding configurable parameters and metadata into the firmware binary during the compilation phase. This preliminary action sets up the structure for future dynamic adjustments, allowing the system to quickly modify parameters at runtime by simply updating the pre-allocated configuration sections rather than recompiling the entire firmware.
2Productivity
If multiple secondary processors operate at different clock frequencies, then the system can be optimized for different tasks, but the hardcoded firmware approach requires separate compiled binaries for each frequency configuration
Solution Approach 1:
The patent creates a universal firmware binary that can serve multiple secondary processors operating at different clock frequencies. By incorporating configurable parameters and metadata that define processor-specific settings, a single firmware binary can be loaded onto multiple SPs with different frequency requirements, eliminating the need to maintain separate compiled binaries for each configuration.
Solution Approach 2:
The patent enables dynamic parameter changes within the firmware by storing clock frequency and other configuration parameters in modifiable sections of the binary. This allows the same firmware binary to adapt its behavior for different SPs by reading and applying the appropriate parameters from the embedded configuration data, rather than requiring different binaries for each parameter set.
3Reliability
If additional hardware addresses are added to store clock frequency information, then the SPs can access runtime frequency data, but the hardware design becomes more complex and requires advance planning
Solution Approach 1:
The patent introduces an intermediary layer in the form of memory-mapped registers that mediate between the SPs and the host processor. These registers provide a standardized interface for SPs to access clock frequency and configuration data stored in host memory, eliminating the need for complex additional hardware while still enabling runtime parameter access through a simple, uniform memory interface.
4Manufacturing precision
If the firmware is recompiled for each parameter change, then the SPs can execute with correct parameters, but the system loses flexibility and responsiveness to runtime changes
Solution Approach 1:
The patent segments the firmware into compile-time configuration data (stored in metadata or header sections) and runtime executable code. This allows the executable code to remain fixed and efficiently compiled, while the configuration data can be dynamically modified at runtime without requiring recompilation of the entire firmware binary.
Data Source
AI summary
Systems and methods are provided for configuration of a secondary processor by a host processor. The host processor can access compiled firmware for the secondary processor, which has a parameter stored at a pre-determined address. The host processor can modify the parameter at the pre-determined address in the firmware to generate a modified firmware for the secondary processor. The host processor can further load the modified firmware into a memory of the secondary processor. The secondary processor can execute the modified firmware having the modified parameter. The host processor can further remodify the parameter in the memory of the secondary processor during runtime without having to recompile the firmware.
