SPDIF is now bundled with Vivado
The Sony/Philips Digital Interconnect Format (SPDIF) and AES3 are digital audio interfaces that implements the International Electronic Commission (IEC) 60958 interface for transmitting and receiving audio data. AES3 and SPDIF at the protocol level are same but use different physical interfaces primarily driven by their end application needs. AES3 is commonly used in professional audio and video equipment where as SPDIF is more popular in the consumer media devices. Xilinx offers a single core to implement the AES3 and SPDIF controller but users should be aware the differences in the physical interfaces. The core also includes standard bus interfaces to the AMBA® AXI4-Lite and AXI4-Stream interfaces, allowing for integration to the IP core with a master system for further processing of audio data. Data collected by the LogiCORE™ IP SPDIF core is stored in the core’s internal FIFO, allowing the system to process a relatively slow audio stream.
