Answer 30:
BEQ (i.e Branch if equal) instruction branches if the contents
of first register and the second
register are equal.
The syntax of BEQ instruction is :
BEQ {first source register's address}, {second source register's address}, branch address
For example: BEQ $5, $0, -6
The BEQ will branch to address -6 (0xFFFFFFFA in hexadecimal) if contents of $5 and $0 are equal.
Hence the answer is:
c. BEQ will branch to address 0xFFFFFFFA
Answer 31:
The MIPS register file has two read ports and one write port.
Hence answer is:
b. Two read ports and one write port

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 register $7 to $10 $21 (contents of register $10 subtract contents of register...
MULTIPLE CHOICE!! If register t0 contains 0 and t1 contains 4, what would the following instruction do? (MIPS) sw $t0, 0($t1) A. Load 4 into register t0 B. Load 0 into register t1 C. Copy the content at memory address, 4, into register t0. D. Copy the contents at memory address, 0, into register t1. E. Copy the contents of register t0 into the memory address, 4. F. Copy the contents of register t1 into the memory address, 0.
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...

EEL4768C Lab Assignment 6 (40 points) Due 7/24/2018, 11:59 pm on Canvas Register file is an important state element of the MIPS processor. Consider the register file shown below. The register file can read and write the data into the registers. The register file has two read ports (A1, A2) and one write port (A3). The width of Al, A2 and A3 is 5 bits. Writing data into the register is synchronized with the clock signal. WE is the write...
Modify the circuit to support a MFCC
instruction.
MFCC Rd instruction: Move From Condition Codes
MFCC copies into the four rightmost bits of Rd the values of the
ALU signals Carry (C), Overflow (O), Zero (Z) and Negative (N) as
they were set by the previous R- type instruction. The remaining 28
bits of Rd are set to zero.
Describe the changes and additions needed for the
single-cycle MIPS processor datapath and control to support this
instruction.
