Hi!
great idea!!!!!!!!
im desperatly looking for AVB (IEEE 802.1BA) adc/dac s. this could be
THE solution...
1. Modules for dac and adc with on-board identifiers
(mixed-signal design)
2. A FPGA-based programmable system board with connectors for
respective modules (high-frequency circuit design)
3. FPGA code for buffers, clocks, and device discovery (VHDL/Verilog
programming)
Did you have a look at opencores.org for IPs?
I2C and I2S cores are available at opencores.org
4. Data transport modules (FPGA code plus hardware
design), could be
USB, FW, ETH, PCI, wireless, etc...
Perhapes two transport modules?
like FW and ETH -> AudioVideoBridging? (they share the same codec
implementation: iec61883-x)
if you like to use it with a laptop, use FW. if you have a little
projectstudio with seperated recording/control room situation it would
integrate in an AVB environment.
The DAW would need to have an AVB ready NIC, means PTP HW timestamping
between PHY and MAC.
At the moment im working on a linux implementaion for AVB, perhaps this
is what i could contribute?
my implementation will be jack a application...
There is an AVB properitarien IP for FPGA, apparently 25000€.
=> there would be the need for opensource implementation.
so i would like to contribute my AVB stuff if/when i got it working ->
estimated deadline july 2012...
after that i would like to have a look at an open AVB IP for FPGA.
bye
