How do I design a
Design a combo –sequential that transfers data from two source registers into a single
destination register. The data transfer is controlled by a control input.
I have already searched on google, and have designed acc to that using 3 registers and a mux.
I have tried it on proteus but the output isn't coming . Please help me

 

What do you mean by transferring data from two source registers into a single destination registers?

If one register has 10110101 in it and the other has 011011011 in it, what are the eight bits in the destination register supposed to end up being?

Your schematic shows many output lines tied together. If one output is producing a 0 and another is producing a 1, what do you expect the state of that line to be?

I used a mux to select a source register either 1 or 2 and dump the output in the destination register.
I dont know how to connect the source registers to the correct pin of mux just followed instructions from gemini.

 

You don't need a multiplexer - your shift registers have got three-state outputs. Just select the OE on the one you want to use.

How to connect outputs of one source register to the input of another source register?

How do I connect the two source registers 8 outputs to one data input of the destination register?

 

hi Makers,
As explained, the the outputs can be set to tri-state
Do you understand tri-state function and its action?

Hi Makers,
This is an example of tri_stating outputs.
