The Microtronix Avalon Multi-port SDRAM Memory Controller IP Core is designed for maximizing the performance of an Intel® Nios® II processor in Avalon' multi-master streaming data systems. Advanced design features enable maximum system clock rates using low speed FPGA's and standard memory devices, lowering your production cost, and saving you money.The Avalon-MM slave ports can be independently clocked allowing the system to be partitioned and optimized to achieve maximum performance. Supporting post memory read and write cycles, the data FIFO's effectively double memory bandwidth on sequential address or FIFO cache hits. FIFO depth can be tailored for either streaming or random access.


    Device Utilization and Performance

    SDRAM Controller: 700 LE's Avalon Random Port: 500 LE's (per port)Avalon Burst Port: 500 LE's (per port)Up 333 MHz DDR2 clock rates.

    Getting Started

    Intel Quartus® Prime II reference designs are supplied for a number of Intel FPGA development boards.
