It contains many useful hardware features including: Xilinx Virtex-II Pro XC2VP30 FPGA 10/100Mbps Ethernet PHY USB port Compact Flash card slot XSGA Video port Audio Codec SATA connectors (2 hosts, 1 target) PS/2 and RS-232 ports High and Low Speed expansion connectors  Virtex-II Pro FPGA Details [Read More]

Timer with Interrupts

Overview In this tutorial we will improve on the Timer peripheral developed in Create a Simple Timer Peripheral. The improvement is achieved by enabling the peripheral to generate an interrupt when the timer expires. The PowerPC then processes the interrupt through an interrupt handler function which gets called whenever the interrupt occurs. In this example, the interrupt handler function will switch the state of the LEDs and reset the timer. [Read More]

Aurora Transceiver for the PLB

Overview In this tutorial we will create a peripheral containing the Aurora core to implement a high speed serial transceiver with a RocketIO MGT. It will be an improved version of the Aurora transceiver developed in the tutorial titled Create an Aurora Transceiver. The improvement is achieved by connecting the peripheral to the PLB rather than the OPB, which allows much faster data transfer by virtue of a wider bus and Direct Memory Access capability.

Known Issues

Below we describe various problems with the XUPV2P board and/or XPS software, and the solution or work-around. No Vista Support for 9.1 or Older Presently, the EDK and ISE platforms versions 9.1 and older do not support Vista. You must upgrade to version 9.2 to operate under Vista. The Onewire Problem Conditions I am using the Digilent XUPV2P board with Xilinx Platform Studio v8.2i. I connect to my XUPV2P board via USB (i. [Read More]

Create an Aurora Transceiver

Overview In this tutorial we will create a peripheral containing the Aurora core to implement a high speed serial transceiver with a RocketIO MGT. The peripheral can be used to connect two XUPV2P boards using the SATA connectors and transfer data between them at 1.5Gbps. To test the design using only one XUPV2P board, we will instantiate two Aurora peripherals, assign them to different RocketIO MGTs and place a SATA cable between them to create a loop-back connection.

Create an Oscillator with a RocketIO MGT

Overview In this tutorial we will use a RocketIO MGT for possibly its simplest application, a programmable oscillator. This can be achieved by feeding the MGT with a repetitive data pattern (e.g. “10101010101010101010”). By changing the data pattern we can adjust the output frequency and duty cycle. Figure: The Oscillator peripheral --> The diagram above illustrates the oscillator peripheral. In it we use 4 registers to store a 4 x 32 bit repeating pattern to be fed to the RocketIO primitive (GT_CUSTOM). [Read More]

Integrating a VHDL Design into a Peripheral

Overview This tutorial is similar to the previous one titled: Integrating a Blackbox into a Peripheral however in this case, instead of integrating an .ngc file into a peripheral, we integrate one or more VHDL files. Sometimes we have a VHDL design that we developed in ISE, or some other program, and we would like to bring it into the EDK as a peripheral. In this tutorial, we will create the same multiplier peripheral as was created in the previous tutorial. [Read More]

Create a Simple Timer Peripheral

Overview In this project, we will add code to a peripheral template generated by the Peripheral Wizard to create a simple timer. The timer peripheral will be used by the PowerPC to make the LEDs flash with a fixed period. Figure: The Timer peripheral The timer will use two registers, one to store the delay period and the other for starting, stopping and checking if the timer has expired. We will call the first register the delay register and the second register the control register. [Read More]

Integrating a Blackbox into a Peripheral

Overview Sometimes we have an .ngc file from CORE Generator (or some other source) that we would like to bring into EDK as a peripheral. This project is a simple example of integrating a blackbox design into a peripheral generated by the Peripheral Wizard. We will first create a blackbox multiplier using the Xilinx CORE Generator and then we will use the generated .ngc file in our peripheral. The multiplier will take in two 16 bit unsigned inputs and have a 32 bit unsigned output. [Read More]
