We have three 4-bit registers A, B, and C available, each with the standard "Load" input. When "Load" is at 1, then 4-bit data available on the input of a register is loaded into the register at the next rising clock edge. Assume registers A and B are already loaded with 4-bit data representing unsigned numbers. We need to design the data path for the following case: If value stored in register A is an odd number, then register C should be loaded with the sum of values present in A and B registers; else, register C should be loaded with binary value 0000. Your design may include standard logic gates, adders, and multiplexers.

Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.
