A fast-starting low-power computer system-on-chip with self-learning function

Abstract

The invention relates to the technical field of computers, in particular to a computer system-on- chip. The quick-start and low-power-consumption computer system-on-chip with the self-learning function comprises a central processing unit and an on-chip mixed cache, and the central processing unit is connected with the on-chip mixed cache. The on-chip mixed cache comprises an on-chip nonvolatile memory, further comprises an on-chip cache and is connected with an out-chip main memory and an external high-capacity nonvolatile memory. The quick-start and low-power-consumption computer system-on-chip with the self-learning function further comprises a system monitoring statistics module, and the system monitoring statistics module is used for obtaining, configuring and loading operating system start-up information and / or heat application program information to the on-chip nonvolatile memory. The power-on time of an operating system and the starting time of a heat application program can be saved on the basis of keeping high performance of the system, and the power consumption produced when data are guided into an internal storage from the external high-capacity nonvolatile memory to be read by the central processing unit can be reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a computer system on chip. Background technique [0002] As far as the hardware system is concerned, most computers mainly adopt two architectures, namely the Von Neumann architecture and the Harvard architecture. The system architecture of the von Neumann structure is as follows figure 1 As shown, a system on chip (System on Chip, SoC) 5 includes a central processing unit (CPU) 1 and an on-chip cache (cache) 2 . The system on chip 5 is connected to an off-chip main memory (mainmemory) 3 and an external non-volatile memory 4 . The central processing unit 1 can directly access the on-chip cache memory 2 and the main memory 3 through the system bus. The data or instructions stored in the external non-volatile memory 4 are first imported into the main memory 3 through the external interconnection bus, and then imported from the main memory 3 into the on-chip cache 2, and the in...

Problems solved by technology

[0006] Seen from the above process, whether it is each power-on of the system or the loading process of the hot application program, the central processing unit 1 always needs to load the operating system startup program or the hot application program from the external non-volatile memory 4 into the main memory 3 , and then import the on-chip cache memory 2, which has the disadvantages of slow speed and high power consumption, and as the system runs longer and more times, along with the wear and tear of electronic devices, the system performance will gradually decline. If the power consumption is not maintained If the speed changes, the system running speed will become slower and slower. If the running speed remains the same, the power consumption will be higher and higher.
