Bus masters diagram

Posted on Feb 7, 2014

It is possible to add bus masters to the system, but a different bus architecture would be required, since the Integrator/CP uses the AHB-Lite bus protocol, which allows only one bus master (the ARM CPU core). One way to add bus masters in a Logic Tile would be to instantiate a bridge in the IM-LT3 FPGA, and splitting the Z[127:0] bus at the IM-LT3.

The custom masters (and slaves) could then exist on the upper segment of this bus, and the Integrator/CP's AHB-Lite System bus would continue to exist on the lower segment of the bus.
