Since 1993 Alpha Data has been providing parallel hardware solutions to help our customers realize their computational goals. 3 ZCU106 VCU TRD design, so this example is setup (architecturally) to be extended to incorporate the other TRD design module capabilities. Select S_AXI and click OK. The next example is the counter but with an additional AXI stream slave interface through which one can configure the counting range of the counter. AMBA 4 AXI DUAL CORTEX A9 @ 1GHz. View Notes - 2 - ds744_axi_gpio from EC EN 427 at Brigham Young University. The BCM2835 system uses an AMBA AXI-compatible interface structure. Last time we discussed how to run desktop Linaro Ubuntu Linux on the ZedBoard. LogiCORE IP AXI GPIO Product Specification LogiCORE IP AXI GPIO v2. In the hardware portion of this example, €a Xilinx AXI timer will be added to the PL fabric and the UART in the PS will be enabled along with other PS peripherals. USB Thumb Drive. This tutorial will show how to load the overlay, and will focus on using the AXI GPIO controllers. It only uses channel 1 of a GPIO device and assumes that the bit 0 of the GPIO is connected to the LED on the HW board. This lab uses the Vivado IP example design. Xilinx Design Flow; Altera Design Flow; Functional Verification. AMBA 4 AXI DUAL CORTEX A9 @ 1GHz. Part 1 is an introduction to ethernet support when using the Micrium BSP. The Block Design window matches FIGURE 11. Information about this and. The second half of the ECE3622 course will consider System-on-Chip (SoC) design for the processor System (PS) using the C language and the AXI/AMBA bus interface to the Programmable Logic (PL). For details, see xgpio_tapp_example. Also included is a NoC interface peripheral that is accessible from the Zynq_PS ARM processors. This document contains a set of tutorials designed to help you debug complex FPGA designs. I soldered the interrupt pin on the board I was working on to a GPIO pin on a different, more generic controller and now Linux is playing nicely with me. This reference design contains Xilinx AXI DMA IP to handle the processor to FPGA fabric data streaming. Provided here for reference. Shortcut to XPS_GUI. Issue 233: XDAC AXI Streaming and DMA. mss file (if not already open). The SPI to AXI4 Controller Bridge IP core enables easy inter-chip board-level interfacing between virtually any microcontroller (MCU) and Xilinx Zynq-7000 AP SoC and FPGAs through the Serial.
