Extending Avalon-MM via LVDS

Extending Avalon-MM via LVDS



The Avalon Memory-Mapped (Avalon-MM) interface is a control-plane interface that can easily be mapped to most peripherals. It can range from an extremely simple localbus interface, to a complex pipelined interface, capable of handling variable latency burst transactions. This reference design of parameterizable IP blocks allows the Avalon-MM interface to be extended across a high-speed LVDS interface between a set of devices. This might be done for various reasons, such as to simply extend the control plane, or to expand the I/O interface of a device for lower-speed signals.
