Draw a block diagram of register file that is described below. Registers are represented as blocks, so you do not need to show each bit. Label all elements, control, and data signals and mark their width. Use any program (the best is MS Word).
The task is to draw a diagram of a register file module. There are 4 registers in the register file. Each of them is 8 bits wide. Register number 0 is a zero register; its content is always 0 and cannot be changed. The register file has one read and one write port: "d_out" and "d_in" respectively, each 8-bit wide.
Ports "rd_addr" and "wr_addr" supply addresses of registers that will be read from or written to and ports "d_out" and "d_in" are data ports. For example: if "rd_addr" is 3, the content of the register 3 will become available on "d_out" port. In addition to these ports, the register file needs to have a "wr_en" that is used to enable writes to a register in the register file.
The register file has input ports for the clock signal "clk" and for the reset signal "reset_N". The reset is asynchronous and active low (note that there is " _N" in its name).
1) MS Word or any other file with the full diagram of the described register module.
Windows, MS Word, etc...
