Draw an arc out of every bubble for every input value. What is the role of the Add units? Which of the above units need a clock? What is being saved (latched) on the rising edge of the clock? Keep in mind that the latched value remains there for an …
we’ll design a simple CPU that executes: basic math (add, sub, and, or,slt) memory access (lw and sw) branch and jump instructions (beq and j)
RISC is a type of CPU design in which it is believed that a simplified instruction set will enhance performance of the processor. It uses a small, highly-optimized set of instructions rather than a
Lw/sw and beq need ALU even though they are I-type instructions. Three cases: address computation for lw/sw, comparison for beq, and R-Type; needs two control lines from the main control unit:
Design of the MIPS Processor We will study the design of a simple version of MIPS that can support the following instructions: • I-type instructions LW, SW • R-type instructions, like ADD, SUB • Conditional branch instruction BEQ • J-type branch instruction J The instruction formats 6-bit 5-bit 5-bit 5-bit 5-bit 5-bit

This homework requires you to design and implement the Duke 250/16, a 16-bit MIPS-like, word- addressed (not byte-addressed) RISC architecture. (A word is 16-bits.)
Branch instructions: beq, j We will approach the CPU design in two stages. First, we design the datapath, i.e., the set of building blocks (like, e.g., ALU, registers, multiplexers, etc.), as well as their connectivity, that is required to enable execution of every single instruction listed above, in …
