CPU time (or process time) is the amount of time for which a central processing unit (CPU) was used for processing instructions of a computer program or operating system, as opposed to elapsed time, which includes for example, waiting for input/output (I/O) operations or entering low-power (idle) mode. The CPU time is measured in clock ticks or seconds. Often, it is useful to measure CPU time as a percentage of the CPU's capacity, which is called the CPU usage.
Intelligent cockpit system based on type i virtualization technology and resource division method thereof
PendingCN122111671AResource allocationSoftware simulation/interpretation/emulationVirtualizationTerm memory
The application relates to an intelligent cockpit system based on a Type I virtualization technology and a resource division method thereof. The system comprises a hardware platform, at least one virtualization-supported processor, memory, storage device and peripheral device; a Type I virtualization management program running on the hardware platform and directly managing hardware resources; a first virtual customer system running an embedded Linux system and used for driving an instrument display screen; and a second virtual customer system running an Android system and used for driving a central control display screen. Two independent customer systems are virtually generated on a single hardware platform through the Type I virtualization management program, and embedded Linux and Android are respectively run to support the functions of the instrument screen and the central control screen. Through CPU time-sharing scheduling, independent memory division, device direct connection and sharing combination, efficient isolation and reuse of resources are realized, so that the hardware resource utilization rate is effectively improved, and the system cost and power consumption are reduced.

Memory recovery method, electronic device, and storage medium
A memory reclamation method, electronic device, and storage medium are disclosed, relating to the field of storage technology. The method is applied to an electronic device. In response to a memory allocation request, when the current amount of free memory is below the high memory threshold but above the low memory threshold, the electronic device can wake up an asynchronous reclamation thread. The electronic device can control the asynchronous reclamation thread to run on a CPU small core and / or based on a second priority, and reclaim memory during operation; wherein the second priority is lower than a first priority pre-set for the asynchronous reclamation thread; the CPU time slice corresponding to the second priority is shorter than the CPU time slice corresponding to the first priority; the CPU time slice represents the maximum duration for which the asynchronous reclamation thread can run continuously on the CPU. This method can alleviate the lag issues caused by memory reclamation in electronic devices.
