[0031] The present invention will be described below with reference to the drawings. As shown in Figure 2, the present invention adds an Ecache to the CPU chip. Ecache is essentially a high-speed memory in the chip. The connection method of Ecache is the same as the cache in the existing computer system, one end is connected to the register, and the other end is connected to the memory in the computer system. In addition, the data transmission between Ecache and memory and registers shares the existing mechanism of the cache.
[0032] Figure 4 is a schematic diagram of the unified addressing and address space division of Ecache and memory. It can be seen from Figure 4 that the Ecache located in the CPU chip and the memory located outside the CPU chip are addressed uniformly, starting from a small address. In the implementation of accessing Ecache, first determine whether the memory access address is
