FINAL TASK

Complete the VHDL code for the $8-$bit computer in Chapter $13$ to run the programs from the attached file, test it using computer$\_$tb$.$ vhd$,$ and observe results with GTKWave.

Step $1$: Identify Key Components

Understand the VHDL code structure for the $8-$bit computer in Chapter $13.$ This typically includes components like the ALU, registers, memory, and control unit.

Step $2$: Extend VHDL Code

Modify and extend the VHDL code to include functionalities required to run the programs provided in the attached file. This might involve adding or modifying instructions, enhancing control logic, or expanding memory capacity.

Step $3$: Test with Testbench

Use the provided testbench file computer$\_$tb$.$vhd to simulate the $8-$bit computer. Ensure that the test programs run as expected by executing the testbench in a VHDL simulator. You should change the content of rom$\_128$x$8\_$sync$.$ vhd according to each case in the attached file.

Step $4$: Analyze Results with GTKWave Use GTKWave to analyze the simulation results. Verify that the output matches the expected behavior of the programs.
