AXI4 supports QoS, AXI3 does NOT suppor QoS. 读交织 ：简单来说，读交织是out of order乱序的其中一种实现形式。. Read Data Interleaving is supported in AXI4 and following is my understanding on Data Interleaving: Multiple Read commands can be executed simultaneously and data interleaving is supported as long as all condition for ordering are followed. Interleaving allows you to send WID transfers for a number of outstanding AW transfers, BUT. I think there would not be big advantages. 4) January 18, 2012 fChapter 4: Migrating to Xilinx AXI Protocols • Implements a read and write data buffer of depth 32x32/64x32 to hold the data for two PLB transfers of highest (16) burst length. configured as AXI3 write data with interleaving (with write interleaving depth >1). Why is the CONNECT method bottom up in UVM? But the reason for being bottom up approach may be because of port export connection in the graph which extends from lower level to high level components and after which connect method can be called which extends from uvm_port_base#IF. The AxiMaster and AxiLiteMaster classes implement AXI masters and are capable of generating read and write operations against AXI slaves. Tune for performance and re-simulate: Ensure that you have the right number of NoC NMUs and DDRMCs to meet your requirements. The build phase is top down because the parent component's build_phase constructs the child. Found this statement: "For a slave that supports write data interleaving, the order in which it receives the first data item of each transaction must be the same as the order in which it receives the addresses for the transactions. Write transaction ID on the GIF is verified for write ID consistency between the AXI and the GIF without write interleaving or out-of-order write responses. value on the address channel. So for the R channel we already have a slave-master flow direction, with accompanying handshake signals, to easily support passing responses for each read. I'm a graduate student living stylish south Korea. sequence_length 1. 4. The AMBA AXI4 Interconnect core connects one or more AXI memory-mapped master devices to one or more memory-mapped slave devices. AXI3: Write data interleaving (for different IDs) is supported. dfblob:120001dbc4d dfblob:c39f478f34a. "The write data interleaving depth is the number of different addresses that are currently pending in the slave interface for which write data can be supplied. The AVI Mux filter takes the video stream from the capture pin and packages it into an AVI stream. While AXI4 supports burst lengths of up to 256 beats.
