Description

Company : SLAC National Accelerator Laboratory

Description: A Proxy module for sending transactions on an AXI-Lite bus.

Usefull for situations with long transactions times, such as when the AXI-Lite bus is bridged to I2C. In this case, the AXI-Lite bus Master could be locked out for some time while waiting for the I2C transaction to complete. This module allows the transaction to be kicked off and then the

response to be polled for later.
