Thank you for your feedback. Course interleaving is enabled with the memory controller mapping to multiple address regions. I'm learn about AMBA 3. The simplified AXI4 Master Protocol supports pipelined requests, so it is not required to wait for the wr_complete signal to be high before issuing a subsequent write request. The AMBA AXI-4 Master is designed in this project, which is modeled in Verilog and simulation results for read/write operation for data/address are shown in VCS tool. Of course it can have a larger addressing space, but again it has to be in the multiples of 4KB. In practice, removing write interleaving from this part of the AMBA standard makes certain aspects of the AXI protocol easier to handle. QoS, Write Data Interleaving, unaligned data transfer, byte invariance. AXI4 supports QoS, AXI3 does NOT suppor QoS. CoreAXI4Interconnect is a configurable core with the following features: • Supports high-bandwidth and low-latency designs. 7. Where interleaving is supported, the WID and RID signals will indicate which of the interleaved transactions the data transfer relates to. Simran Sarai 2014. The Advanced eXtensible Interface ( AXI) is an on-chip communication bus protocol and is part of the Advanced Microcontroller Bus Architecture specification (AMBA).
