LatticeECP3 memory usage guide

Posted: 20 May 2009 ?? ?Print Version ?Bookmark and Share

Keywords:FPGA? RAM? memory?

This technical application note discusses memory usage for the LatticeECP3 family of FPGA devices. It is intended to be used by design engineers as a guide to integrating the Embedded Block RAM (EBR)- and PFU-based memories for this device family in ispLEVER.

The LatticeECP3 architecture provides many resources for memory-intensive applications. The sysMEM EBR compliments its distributed PFU-based memory. Single-Port RAM, Dual-Port RAM, Pseudo Dual-Port RAM and ROM memories can be constructed using the EBR. The LUTs and PFUs can implement Distributed Single-Port RAM, Dual-Port RAM and ROM. The internal logic of the device can be used to configure the memory elements as FIFO and other storage types.
