This is on a Xilinx Spartan 6 FPGA and I plan on using the EDK AXI4 Interconnect IP, which has a minimum WDATA width of 32 bits. At first I wanted to use narrow burst, i.e. AWSIZE = x"01" (2 bytes in transfer).

May 27, 2013 · This project implements the AXI4 transaction-level model (TLM) and bus functional model (BFM) in VHDL. Currently, only the AXI4-Stream Master protocol is supported, but I also have plans to support AXI4-Lite and the full AXI4 protocols. This enables sub-components of an SoC system to easily communicate with one another through the AXI4 bus. The AXI4 interface standard is pretty lengthy, and super powerful. For now, we are going to use it's simplest form of AXI4-Lite. This is a very simple register base interaction between a master (ARM Core) and slave (our super awesome peripheral).

As AXI uses the byte addresses and IPbus uses word addresses, the AXI address is shifted right by 2 bits (divided by 4). As IPbus does not support single byte accesses, the bridge allows only accesses
The Master I/O data interfaces use an AXI3 bus, forward compatible with AXI4 interconnects. The input/output interfaces of the JPEGE IP core are the following: Configuration Interface: AXI-Lite slave with a 32 bits interface to control all the necessary parameters of encoding. ACE-Lite masters can still snoop ACE master caches, but other masters cannot snoop ACE-Lite master's caches. ACE-Lite also supports barriers. The AXI4 protocol is an update to AXI3 that enhances the performance and use of the interconnect, when used by multiple masters.
AMBA is a freely available open standard for the connection and management of functional blocks in a system-on-chip. AMBA specifications are widely adopted as the standard for on-chip communication and provide a standard interface for IP re-use. Dear all, I am developing a custom AXI IP using vivado. it has axi-stream slave and axi4-full master interface. my goal is to connect the master interface to zed board HP0 (axi3 slave interface). Since the input is the input and output axi standards are different i dont know how to map the input AXI stream signal to AXI4 ful master interface.
the AXI4-Stream transactions start three clocks after WDATA is accepted from the AXI4-Lite/ AXI4 interface. Throughput The throughput varies depending on the configuration of the AXI4-Stream FIFO core. For example, if the Data Interface is configured as AXI4-Lite, the throughput is less because the core can accept WDATA once in three clock cycles. I'm implementing an AXI4-Stream module. The module uses three DSP blocks (DSP49E1, UG479 - Xilinx). In order to run the module at a frequency of 150 MHz, the design is a pipeline going successively ...
