12.2.6.1. Block Diagram
The following block diagram shows the connectivity between the HPS, MPFE, MPFE-lite, Fabric, and two IOBank blocks. Some members of the Agilex™ 5 series support two IOBank blocks and therefore support both the MPFE and MPFE-lite blocks. Some members of the Agilex™ 5 series support only one IOBank block, and therefore, only supports the MPFE block, eliminating the MPFE-lite block.
- The 512/256/128-bit F2H port in previous family devices has been split into a 256-bit F2H and a 256/128/64-bit F2SDRAM.
- This also eliminates the FPGA-to-CCU port from MPFE to HPS.
- In previous family devices, the 512-bit CCU_MEM0 port has been split into two 256-bit AXI4 ports (DMI0 and DMI1), allowing the CCU/NCORE to interleave between the DMI0 and DMI1 ports.
- Since the Hard Memory Controller Adaptor (HMCA) has been removed from the MPFE, the 512-bit OCP interface to IOBank in previous generations has been replaced with two 256-bit AXI4 ports to IOBank.
- Similarly, the core2seq/seq2core interface between the HMCA and IOBank in previous generations have been replaced with a 32-bit AXI-lite interface to IOBank_0.
- The MPFE adds two 256-bit AXI4 ports for data read/write accesses to IOBank_1 and a 32-bit AXI-lite interface for register accesses to IOBank_1:
- Access to these ports shall generate an error if IOBank_1 is not implemented on a given device.
- The ATB trace observer routes directly to the CoreSight* subsystem in the PSS, rather than going through the fabric, to make it easier for you to trace the data flows through the MPFE NOC.
- The TBU to TCU communication still utilizes two unidirectional AXI-streaming interfaces.
- The MPFE_CSR port increases to a 64-bit AXI4 port due to the new NCORE not supporting 32-bit interfaces.
