An implementation scheme for multi-port memory controller was proposed.This controller can support six AHB interfaces for accessing external memory
support SRAM
ROM
NOR-FLASH
SDR-SDRAM and DDR-SDRAM.The arbiter in it uses fixed priority combined with timeout arbitration strategy.Based on the SMIC 0.13 μm standard cell library
area of the chip is about 230653 μm2
system clock is 130 MHz.FPGA simulations show that the implementation scheme can improve system performance significantly.
