Selects Which

Create a Register File in VHDL that contains the register module, multiplexer, and decoder that you have previously written in vhdl.

The register file contains eight register modules and follows a two-read, one-write format. See Figure 2 below.

Inputs (One bit unless noted otherwise):

rd1, rd2 (3 bits): Read1 and read2. Selects which registers to read from.

wr (3 bits): Write. Selects which register to write to.

Note that the previous signals are 3 bits long, allow them to address all eight registers.

in (16 bits): Data to be written to the appropriate register.

clk: Clock signal.

we: Write enable. Enabling allows register contents to be written.

rst: Resets all registers. Asynchronous. Can be active high or low.

Outputs:

out1, out2 (16 bits): Parallel outputs containing the data from the selected registers.

Hints

-Use the output of the 3-to-8 decoder in conjunction with the register files we signal to in drive the we on the register

-Use two 8-to-1 MUXs, one to connect thenoutput of the register specified by rd1 to out1, and a second for rd2 and out2.

-Do not use parameters in the entity of the register file, however, generics should still be used when instantiating the various components. (Note: The reason for this is that the generic would then have to be set in a higher level, of which there are none.)
