LatticeECP3 is the first and only PCI Express 2.0 compliant low-cost FPGA. The PCI Express 2.0 specification allows operation at a lower speed than PCI Express 1.1 (2.5 Gbps), but the loop bandwidth characteristics are different and more rigorous. Now designers who need PCI Express 2.0 compliance, but do not need the PCI Express link to operate at 5 Gbps, can use the low-cost LatticeECP3 FPGA in PCI Express 2.0 compliant systems.
DMA Demo Block Diagram
The Scatter-Gather DMA IP core, together with the PCI Express Endpoint IP core, demonstrates moving data between the Lattice FPGA and PC system memory using a LatticeECP3 Versa Evaluation Board. The board uses the PCI Express link as both control (setup and operation of the core) and data path (DMA to/from PC system memory). The PC provides the test platform (power, run-time environment) and the user interface.
