2D Matrix Array

Problem Description

Implement a 4x4 matrix memory module that supports both read and write operations. The matrix should store 8-bit values and allow access via row and column selectors.

Module Interface

• Inputs:
  • clk: Clock signal
  • reset: Reset signal (active high)
  • row_sel: 2-bit row selector
  • col_sel: 2-bit column selector
  • wr_en: Write enable signal
  • din: 8-bit data input
• Output:
  • dout: 8-bit data output

Expected Behavior

• On reset: All matrix elements initialized to 0
• When wr_en = 1: Write din to matrix[row_sel][col_sel]
• When wr_en = 0: Read matrix[row_sel][col_sel] to dout
