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.

3. Compile the following high-level code into RISC-V pseudo assembly language. Assume variable a and val are stored in memory as words. Make sure you load these values into registers before you use them and store back any changes to memory. You can use "Iw x5, a" and "sw x5, a" as pseudoinstructions for load and store a word for variable a, considering a is a symbol for the address of the memory that store the value of a. This question is for you to practice using shift-logic instruction, logic (AND, OR, etc) instructions as well as branch instructions.
