The Verien Design Group MADI IP core is proven technology. Many of these cores have been shipped and to some of the biggest names in the audio industry - both in the US and in Japan.
The Multi-channel Audio Digital Interface (MADI) is an AES standard, specifically AES-10, and can accommodate the bidirectional transfer of up to 64 channels of audio data across either copper or fibre. The Verien MADI core consists of both the transmitter and receiver and can be dynamically configured for up to the maximum channel count supported by the standard. The receiver includes data recovery using an oversampling technique - no high speed transceivers (Hotlink or otherwise) are required and no external clock recovery is needed.
The user side consists of two simple FIFO interfaces - one for the transmitter and one for the receiver, along with programmable FIFO status signals. Example interface code and multiple example designs are provided, including three self-checking testbenches. Loopback generation and checking are built-into the core allowing the core to be tested without external hardware.
