TinyMicro program counter X83229

Design the program counter of the TinyMicro. After reset, the program counter must have the value zero. The value will be modified at each cycle the counter is enabled. If signal jump is asserted, the program counter will be loaded with jump_address, otherwise it will be increased by one.

The number of bits of the program counter must be a parameter (N) with the default value shown in the specification.

Specification

module program_counter(pc, jump_address, enable, jump, clk, rst);
    parameter N=6;
    output [N-1:0] pc;
    input [N-1:0] jump_address;
    input enable, jump, clk, rst;

Input

• enable is the signal the enables the change of the program counter value.

• jump is the signal that indicates that the program counter must be loaded with a new address.

• jump_address is the new value that must be stored in the program counter whem jump is asserted.

• clk is the clock signal of the circuit.

• rst is the reset signal of the circuit.

Output

• pc is the value of the program counter.
