Usc only the following MIPS instructions for assignment questions 3, 4 and 5: add, sub, addi, j, beq, bne, lw, sw. You may not need as many lines as we provide space for 4. (4 pts) Write a MIPS program starting at address 20 that writes a value of 488 to register $7. Next, you will test if register $10 is equal to register $7. If the values are equal, continue execution at address 48; otherwise set the value in...

Consider a machine which implements an ISA in which every
instruction is 32 bits long and has the following format:
Where DR = Destination Register, SR = Source Register, and
IMMVAL = Immediate Value. The fields DR, SR are represented using
the same number of bits.
If there are 7 bits for the opcode and 16 registers,
A.) How many unique opcodes can be represented?
B.) What is the minimum number of bits required for the source
register (SR) field?...

Question 1 Figure 1 shows a datapath for R-type instructions which consits of a register file and an arithmetic logic unit (ALU). These instructions are also known as aritmetic-logical- instructions since they perform aritmetic or logical operations. The register file contains all the registers and provides two read ports and one write port. The register file always provides the contents of the registers corresponding to the read register inputs on the outputs, while the writes must be explicitly controlled with...

Exercise 1 (9 pts) We have seen that ARM has 16*32 bits registers (plus floating point registers) There is also a status register: CPSR. It contains, among other things, the following important status bits N Negative, set when the result of an arithmetic operation is negative (according to the two's complement encoding of the natural numbers . Z- Zero, set when the result of an operation is zero . C Carry, set when an operation results in a carry bit...

Though this is an R-type instruction, but it is a special one that has the opcode being 000001 (instead of 000000), so the control unit will be able to differentiate this jlr instruction from the other R-type instructions and generate a special set of controls for this instruction.

Assume that a 32 bit bit pattern already held in $ to has the following fields. Write instructions to extract the fields as indicated. Each can be done in two ox three instructions. So, field A is one bit wide in bit 31, and field E is 6 bits wide in bits 9 - 4, etc. Convert field C into an unsigned 32 bit value in register $t.2. Test the bit in field G and branch to LABEL if (and...
