Accumulator X74712

Design a circuit that accumulates the values received at the input. The circuit receives an 8-bit input and generates an 8-bit output that represents the sum of all the inputs received at the previous cycles. After rst is asserted, the output must be zero. The following waveform illustrates the operation of the circuit.

Specification

module accumulator(in, out, clk, rst); input [7:0] in; input clk, rst; output [7:0] out;

Input

• in represents the 8-bit input number.
• clk is the clock signal.
• rst is the reset signal.

Output

• out represents the 8-bit output.
