Serial adder vhdl source code

Create an internal signal, e. On a further note, your tmp signal is not necessary. At the top of your file do this and your problems should go away:. Also don't put signal h in your process sensitivity list. That process is a clocked process and you shouldn't have any signal but your clock and an asynchronous reset in the sensitivity list if you're using an async reset.

You don't need a reset at all here. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. Learn more. This is the code for a serial adder of 6 bit numbers in VHDL. In this we are using three shift registers which are used to hold A, B and Sum. Now in each clock cycle, a pair of bits is added by the adder FSM and at the end of the cycle, the resulting sum is shifted into the Sum register. Let G and H denote the states where the carry-in-values are 0 and 1.

Output value s depends on both the state and the present value of inputs a and b. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name. Email Required, but never shown. The Overflow Blog.

Input signal are also clk, load and clear. Clk is the clock, load is to write the x,y value in the registers while clear is to clear registers and flip flop.
