A cpu, an electronic device and a cpu cache control method

Abstract

The present application discloses a CPU, which includes a CPU body, and further includes: a second processor interconnection interface for detachable connection with the first processor interconnection interface of the CPU body; connected with the second processor interconnection interface, for providing The bus protocol module of the bus protocol; the cache read-write control module connected with the bus protocol module for controlling the read-write operation; the cache memory used for cache data information connected with the cache read-write control module. The CPU provided by this application can increase or decrease the cache space according to actual needs, and can conveniently and flexibly adjust the cache space of the CPU. On the one hand, it can improve the hit rate of the CPU cache space, thereby improving the work efficiency of the CPU and improving system performance; on the other hand, A waste of cache space can be avoided. The application also discloses an electronic device and a CPU cache control method, both of which have the above beneficial effects.

Description

technical field [0001] The invention relates to the field of chip control, in particular to a CPU, an electronic device and a CPU cache control method. Background technique [0002] In recent years, with the rapid development of computer technology, the requirements for CPU performance are getting higher and higher. The performance of the CPU affects the performance of the entire system, and the size of the cache space of the CPU affects the performance of the CPU. During the chip design process, the size of the cache space of the CPU is determined by the size of the cache space set in the cache memory of the CPU. In practical applications, when the system needs to be used in various scenarios, if the cache space of the CPU used is small, the cache space will be insufficient during use, which will cause low CPU performance efficiency; Directly select a CPU with a large cache space, but in practical applications when a large-capacity cache is not needed most of the time, it...
