Digilent nexys 2 board reference manual
Chapman, PicoBlaze for Spartan-6, Virtex-6, and 7-Series (kcpsm6) - Reference Manual, example final fantasy game 7 of a circuit based on PicoBlaze: assembly code, vHDL code, exercises: Lab Exercise 1 : specification.
In the next figure you can see the truth table for the 2-bit comparator circuit.Select Place » Component and place the following components on the workspace: Component Group Family AND4 PLD Logic logic_gates xnor2 (4 gates) PLD Logic logic_gates Wire the circuit as shown in the next figure.Start a uart terminal (set to appropiate baud rate) and then program the device using the bit file provided in the project *.zip archive, located in the sw folder (./ad7193/sw/t).ISE In-Depth Tutorial, section: Creating a core Generator Tool Module.HW Platform(s The bit file provided in the project *.zip file combines the fpga bit file and the SDK elf files.To begin, connect the PmodAD5 to JA connector of ZedBoard (see image below).If the binary quantities are equal, the output will generate a high level.Lecture slides: Power Point, to print N slides per page, please choose Print, Options: Print what: Handouts, Handouts: Slides per page: N, recommended Tools, Files, Manuals, and Examples: openpicide.The probe will illuminate when the inputs are exactly equal.Following the same approach, we can build a 4-bit comparator using four xnor gates and one AND gate with four inputs, as shown below:.After programming the AD7193, the program will display the values of all internal registers.
The compiler is different: XC32 instead of C32.
Read Voltage Values referenced to aincom, unipolar Mode.
Return to the top level circuit and run the simulation to verify the operation of the parallel binary comparator.
Simulation, in this section we use the Multisim PLD Schematic to simulate the 4-bit parallel binary comparator.Click, finish and place the PLD subcircuit on the workspace.When using the ZedBoard reference design in order to develop your own software, please make sure that the following options are set in system_config.And then the main function is written.Read Voltage Values referenced to aincom, bipolar Mode.Provide a name for the PLD subcircuit and click.SW0 to, sW7 which correspond to the slide switches in the physical board.The on-chip.92 MHz clock can be used as the clock source to the ADC or, alternatively, an external clock or crystal can be used.In order to compare binary numbers with two bits each, we can use an additional xnor gate and an AND gate, as shown below: As you can see, one of the xnor gates compares.
