1.4. System Level Block Diagram

The system-level block diagram shows an overview of the interfaces on the DR Controller and the blocks that these interfaces are connected to. In the DR flow, the HSSI Dynamic Reconfiguration IP Generation step in the compilation flow generates DR MIF files and RTL for a HSSI Dynamic Reconfiguration IP for each DR Controller Group. Each DR controller group is associated with a separate DR Controller, which connects to a QHIP specific to that group.
The following three interfaces connect the DR Controller to the generated QHIP, and you need to manually establish these connections:
  • Mux Sel Interface: Manages select signals used to perform muxing between the protocol IPs included in the DR Controller Group.
  • LAVMM: One local AVMM interface per channel is used in the generated QHIP to access both the HIP and the Common SIP, including the Channel SRC
  • SRC Interface: Includes a request and grant interface per channel, which is used to pause and reset operations of the Channel SRCs.
Figure 1. System Level Block Diagram

The 1-channel Common SIP includes the Channel SRC and an AVMM decoder, allowing you to use the same LAVMM interface to access both the Channel SRC and the HIP. The DR Arbiter allows both the currently active SIP and the DR Controller interface with the HIP LAVMM interface. The DR Mux multiplexes other signals between the HIP and SIPs based on the Mux Sel interface input.
