Question

Please provide me the correct answers The Instruction ROM used for the PicoBlaze processor uses the RAMB16_S9_S 18 primitive. Using the Xilinx Spartan-3E Libraries Guide for HDL Designs.pdf document, describe the configurations of this memory module. The structure of the assembly program software.psm can be described as an endless loop. The system clock being used for a PicoBlaze project on the BASYS board is 50 MHz. Using this value and your understanding of the PicoBlaze instruction execution process, calculate the iteration time in seconds for the "loop" loop within the distributed software.psm program file. Explain what the following PicoBlaze assembly instructions are performing. Go: COMPARE test, 01 JUMP Z, End SRO test JUMP Go End:... Develop the Verilog code to interface the 8 switches at port ID 01 h and the 4 pushbuttons at port ID 02h. You may use the 8 switches to send a value to the seven segment display and use the push buttons to light the led lights

Explanation / Answer

In the above mentioned code, a label GO is mentioned first up. Next, the value of test is compared with 1. some example COMPARE statements are as follows. :

COMPARE s0, CR

COMPARE s2, line_buffer_start etc.

If found true, the control jumps to the label End.

else the next line shifts mask to next bit and jumps to a label Go.
