Method for realizing overclocking of kernel time slice

Abstract

For applications, multitasking is a realistic need; and for a processor technology, programming is a theoretical basis of the processor technology. The problem that any processor technology cannot escape is to meet the requirement for multiple tasks on the basis of the programmed technology, and therefore the concept of time slice is achieved. The definition of the time slice or the related technology, namely a time division multiplexing technology for kernel hardware resources, is not easy to understand, and the definition or the related technology is just done in the existing background technology. However, how to define the length of the time slice is often limited by the requirements of the dominant frequency and application of a processor for real-time characteristics. According to the technology, the problem of trade-off between the time slice and actual requirements is solved theoretically and practically, and on the premise that the time slice is set, actual application (namely, on the premise that the time slice is defined as T, 2T, 3T or even more actual execution time slices can be obtained) with an overclocking effect is achieved for the application.

Description

technical field [0001] The invention relates to the field of integrated circuits and computers, in particular to a method for realizing kernel time slice overclocking. Background technique [0002] "Time slices" are defined as long or short trade-offs depending on the real-time nature of the processes inside the processor and the number of processes. The real-time characteristics of the system require that all processes must be executed at least once in a unit of time, that is, the waiting time of a process in the processor waiting to obtain the next "time slice" should not exceed the time required by the real-time characteristics of the system. Hereinafter, the duration required by the real-time characteristics of the system is abbreviated as SAT, which is the abbreviation of System Aging Time, and the "time slice" is abbreviated as TS, which is the abbreviation of Time Slice. [0003] Assuming that the number of processor cores is N, and the number of processes in the p...

However, pushing up the N value still cannot improve the pressure on the system bandwidth caused by too frequent process context switching, nor can it change the state of the kernel's actual operating efficiency.
