axi 1500

The Axi full name advanced Extensible Interface is an interface protocol that Xilinx introduced from the 6 series FPGA, primarily describing the way data is transferred between the master and slave devices. Continue to use in Zynq, version is AXI4, so we often see AXI4.0,ZYNQ internal devices have Axi interface. In fact, Axi is a part of the AMBA (Advanced microc

IntroductionThe AXI protocol is probably a protocol that we often encounter in our usual circuit design, and it's a good deal, and we'll be familiar with this section.At first glance, the AXI protocol signals are numerous, dazzling and easy to Fameng. But in fact its basic idea is very simple. Just grasp the following points:1,valid/ready protocolThe Axi protocol

Label:Although Xilinx has encapsulated the details of the Axi timing and given the official IP and wizard-generated custom IPs, the user only has to focus on their own logic implementation, but it is still necessary to understand the timing of Axi, after all, we do hardware design. AXI (Advanced extensible Interface) is a bus protocol that is proposed by arm for

Reg_data_out In return to this frame diagram:Here, our Axi IP has the ability to interact with ZYNQ and VGA, it is the bridge between PS and PL, now we are only a VGA IP, and this IP is a common IP, yes, "MiZ702 study notes 12--encapsulation of a common VGA IP," said , we will modify the program slightly, in the IP packaging, we can get.Finally, we add these IP, respectively, to complete the hardware to build the connection. Actually, I'll mention so

Purpose: Customizes an IP core and connects to the arm system through the Axi bus. Environment: Win7 32bit Vivado2014.4.1 Xilinx sdk2014.4 Development Board: Zc702 Step 1: Create a custom HDL module. In this experiment, create a 16-bit calculator and save it as test. V. The Code is as follows: Module test ( Input [15: 0], Input [15: 0] B, Input CLK, Output Reg [15:0] sum ); [Email protected] (posedge CLK) Begin Sum End Endmodule Step 2: Create an

At present, the AMBA2.0 AHB Bus specification and AMBA3.0 Axi Bus specifications designed by ARM are being widely used in various SOC chip designs. Their standards for interfacing and interconnection contribute to modular design to accommodate the need for ultra-large scale soc design.The Axi bus is very distinct compared to the AHB bus: Divided into 5 independent channels, unidirectional transmiss

Added the AXI4 specification (the specification for in-SOC IP interconnect developed by ARM and XILINX), with the addition of the Advanced System Bus (ASB) and advanced Peripheral Bus (APB) to the latest version of AMBA4.0, from the very beginning of the AMBA1.0 version definition to the AHB APB, the Advanced tracking bus ATB, et. The AHP APB Axi can be considered as the bus protocol or specification within the scope CPU, however we often refer to the
