help needed to switch from Avalon MM to Avalon ST interface

Hi,

Thanks for your reply. My project is in video domain. I have to process different video formats coming from on board ADVs using IP core provided by Altera and transferred to Media processor (MP) or DAC depending on I2C interface configuration from MP.

The switch from Avalon MM to Avalon ST interface is required for transferring Audio, Metadata, TSData and config data over VLYNQ interface to MP. Currently audio and metadata is transferred by Avalon MM interface, others are still need to implement. So due to Avalon MM interface, it generates arbitration logic which increases data propogation delay throughout the system. System became more complex and unable to scale the future requirements.

We are using VLYNQ IP core from TES. It has built-in Avalon MM interface for exchange of information. And is it a good idea to modify third party IP core? Other modules like MetaDataCapture, I2S module and data_transfer has Avalon MM interface. So please suggest me some way out of it.

Waiting for your reply......
