Write vhdl code for a ram that has 16 locations each 32 bits wide. there will be a chipselect (cs) input that activates the chip. another input to the circuit is an r/w which determines if the operation is a read or a write to the chip. the address input to the chip is a vector. the input and output would also be a vector(s) that should send and receive the data, depending on the address input to the chip.
