FIFO memory capable of configuring multiple ports

Abstract

The embodiment of the invention discloses an FIFO memory capable of configuring multiple ports. A specific embodiment of the memory comprises a plurality of read ports and a plurality of write ports;the memory bank is divided into a plurality of sub-memory banks; one end of each sub-memory bank is connected with a plurality of writing ports, and the other end of each sub-memory bank is connectedwith a plurality of reading ports; each write selector component in the plurality of write selector components is arranged between one write port and the memory bank, and the write selector componentsare used for determining sub-memory banks in which data is written; each read selector assembly of the plurality of read selector assemblies is disposed between one read port and the bank, the read selector assemblies being configured to determine a sub-bank of data read. According to the embodiment, the memory bank is divided into a plurality of sub-memory banks, and the sub-memory banks for writing and reading data are determined by using the writing selector assembly and the reading selector assembly. Therefore, the memory bank can be fully utilized, and resource waste of the memory bank is avoided.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of integrated circuit design, and in particular to a FIFO memory with configurable multi-ports. Background technique [0002] FIFO memory (First Input First Output) is a first-in first-out dual-port buffer. The above-mentioned FIFO memory is usually used for data buffering, so as to alleviate the problem of poor processing capabilities of the data sending end and the receiving end within a short period of time. [0003] In the case of a multi-channel data transmission system, it is necessary to configure a matching number of data transmission channels, and at the same time configure a FIFO memory with a capacity matching the data specification on each of the above data transmission channels to stabilize the risk of overflow caused by data transmission. [0004] However, in actual working conditions, some data transmission channels do not work continuously, which causes part of the FIFO memo...
