Dual port sram profile

　　

Dual port RAM is on a SRAM memory has two sets of completely independent data read and write, address line and the line of control, and allows the two independent systems at the same time the randomness of the memory access.The Shared multiport memory.Dual port RAM the biggest characteristic is to store data sharing.A storage device is equipped with two sets of independent address, data and control line, to allow two separate CPU or controller asynchronously access storage unit at the same time.

　　

Because data sharing, there must be access control of arbitration.Internal arbitration logic control provides the following functions: access to the same address unit of sequential control;Access storage unit block of data distribution;Signal switching logic (such as interrupt signal).Dual port RAM can be used to improve the throughput of RAM, is suitable for caching data in real time.
