Multiple port memory access control module

Abstract

The multi-port memory access control module can be respectively connected to multi external FIFO memories and DRAMs; said multi-port memory access control module has multi access ports; the data access bus width of access port can be adjusted in order to have same width with the packaging/de-packaging device; an internal FIFO memory used for adjusting the user's interface and memory clock pulse domain and an address progression counter used for generating access addresses are also included.

Description

Technical field [0001] The present invention relates to a multi-port memory access control module with storage function in data processing, in particular to a multi-port memory access control module with storage function used in the fields of image or sound effect data processing, data gain, motor control, etc. Control module. Background technique [0002] At present, with the vigorous development of high technology and the popularization of technology products, memory has become an indispensable electronic component in various electronic products. Therefore, all kinds of digital data storage, image data processing, image data debugging, video Data compression, audio data gain, motor control, etc., all use memory as a temporary or permanent storage medium. [0003] Take data processing as an example. Under the situation that the amount of processed data is getting larger and larger, the required temporary storage memory capacity will increase accordingly. The previous first-in-fi...

Problems solved by technology

[0005] To sum up, in the field of technological applications where the amount of data input / output is increasing and the processing is becoming more and more complex, the traditional FIFO memory has insufficient capacity and speed; Instead, it is a larger-capacity dynamic random access memory, but because of its difficult design of control logic, access control is a major bottleneck; therefore, how to use the multiplexing formed by programmable logic gate arrays device, and how to retain the advantages of high reuse rate and easy operation of the first-in-first-out queue interface data, as well as the advantages of larger capacity and lower price dynamic random access memory, etc., are the directions for improvement of related companies
