Abstract

The invention discloses a read-write control method of an RAM (Random Access Memory), which comprises the following steps of: a, inputting external data into an input module of an RAM control top layer, and acquiring bit width information of the input data; b, configuring the bit width ratio of input data in the input module and the bit width ratio of output data in the output module of the RAM control top layer according to the bit width information of the RAM; c, generating an RAM write enable signal and write address information, and writing external data into the RAM according to the bit width ratio of the input data in the input module; and d, generating an RAM read enable signal and read address information, and reading the data from the RAM to the output module according to the bit width ratio of the output data in the output module. According to the RAM read-write control method, the repeated work of developers is reduced, the method can be suitable for different modules in the same project and different project modules, and the universality is improved.

Description

technical field [0001] The invention relates to the field of data cache interaction, and more particularly relates to a method for controlling reading and writing of RAM. Background technique [0002] Random access memory (English: Random Access Memory, abbreviation: RAM), also called main memory, is an internal memory that directly exchanges data with the CPU. It can be read and written at any time, and the speed is very fast, and it is usually used as a temporary data storage medium for operating systems or other running programs. When RAM is working, data can be written or read from any specified address at any time. It is used in computers and digital systems to temporarily store programs, data, and intermediate results; therefore, RAM is widely used in various data cache interaction fields. For example, in a project that involves functions such as data caching, DMA operation, and data flow interaction, the RAM bit width is 64 bits, the data bit width of module A is 32...
