BRAM Efficient Multi-ported Memory on FPGA

Abstract

Multi-ported memory is broadly used in modern designs on FPGAs. However, the excessive demand on BRAMs to implement multi-ported memory on FPGA would block the usage of BRAMs for other parts of a design. This issue becomes a serious concern especially for designs that require huge internal storage capacity. This paper proposes a BRAM efficient scheme on increasing read ports and write ports. When compared with previous works, the proposed multi-ported memory can reduce up to 53% requirement on BRAMs with only minor frequency degradation.
