Question # 2

addi $t0,$t0,400 21/ This will add 400 toto il A lw $87, O($t0) " This will load the value from the as addi $87, $87,1 sw $7,($t1) (4 11 This will incrense value by one" subi $t0, $t0, 4 S ul This will store Valve to the other bne $t1 $s0 A all This will substract indes by 0 " This will loop untill tl is 2. You are tasked with designing a CPU with 40-bit wordsize. You are using a RISC instruction set, similar to MIPS, with about 300 instruction codes. You will need at least R-format (3 register and instruction code) and I-format (2 register, a 20 bit data field and instruction code). Draw a diagram of fields in each 40 bit instruction format, label each field with its function and size. How many registers do you have? Are the registers all usable in every instructic position (general purpose, like MIPS), or are some registers special purpose? On a 32-bit MIPS machine, you need to execute the following single-pre loating point arithmetic instructions: 1. 3.5e25 * 3.5e25 / 12.0c20
