Problems solved by technology

The characteristics of the above-mentioned addition operation time consumption will be directly reflected in the existing technology; when image 3 In the prior art, when the subtraction operation carried out by the subtraction module is used to compare the size relationship between the given address 54 and each end address 46A to 46D, it will consume a considerable amount of time on the subtraction operation, and cause the existing control circuit 28 The efficiency of preliminary address decoding is low, and it is impossible to quickly decode the memory module to which a given address belongs
Once the efficiency of address decoding is low, the central processing unit 12 (see figure 1 ) will not be able to access the storage resources of the storage device 16 quickly and efficiently, so that the efficiency of the operation of the entire computer 10 cannot be effectively improved

Abstract

The method and related device for decoding the addresses of the memory determine what segment the given addresses are located on. The storage device contains multiple segments. Each segment contains multiple storage units. Each storage unit possesses the relevant address. The method compares whether the part of bits in the given addresses is accorded with any one of bit modules so as to determine what segment the given addresses belongs to.

Description

technical field [0001] The present invention relates to a storage device address decoding method and a related device, in particular to a method and a related device for rapidly performing address decoding by bit pattern comparison. Background technique [0002] In a modern society, a microprocessor system that can quickly process and manage various digital data, files, data and audio-visual information has become one of the most important basic equipment for the information society. Generally speaking, in order to realize various complex and diversified functions, the microprocessor system will set up a temporary data storage device (such as a random access memory) to temporarily store the programs and data required during the operation of the microprocessor. . The microprocessor reads and executes the programs and data temporarily stored in the storage device, and can control the microprocessor system to complete various functions. Therefore, the speed and efficiency wit...
