DesignWare Multi-Port Memory & Asynchronous Register File

Synopsys' four-port register file memory compilers and asynchronous register file memory compilers address the requirements of designers in the networking and communications markets.

The four-port register file memory compilers have two write ports and two read ports, providing parallel memory access most suitable for compute-intensive applications that require extreme bandwidth capabilities.The high-speed pseudo four-port and pseudo quad-port SRAM architectures in 7nm support parallel operations with significant area reduction. The P4P and PQP allows up to two and four simultaneous read or write operations respectively.

The asynchronous register file memories have one synchronous write port and one asynchronous read port.
