Write a single 16-bit LC-3
instruction (in binary) that clears all the bits of R6 except the
least significant two bits.
Write a single 16-bit LC-3 instruction (in binary) that clears all the bits of R6 except the least significant two bits. In other words, after your instruction executes, bits O and 1 of R6 will be unchanged, and the rest of R6 will be zero. Answer:
31. A A digital computer has a memory unit with 32 bits per word. The instruction set consists of 128 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. How many bits are left for the address part of the instruction. 7 bits 17 bits 25 bits 32 bits
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 3 (10 points) Convert the following MIPS assembly code into machine language. Write the instruction in hexadecimal. The opcode for sw 43 (101011). sw St1, -4(St3) Question 4 (10 points) Consider the following MIPS assembly code: addi $s3, $0, 5 addi $s1, S0, 3 addi Ss1, $s1, 2 beq Ss3, Ssl, target addi Ss1, Ss1, 1 target: add Ss3, Ss1, Ssl a. After running the code, what is the value of Ss3? b. If the memory address of the...
Should be written in Python: A disassembler takes a machine code file (binary) and converts it back into assembly code. Disassemblers are a key tool in the software reverse engineering process because it allows you to go from the raw binary all the way back to the original source code, if desired. For this assignment you will be given 8 32-bit binary strings and the type of the instruction (I-type, R-type, or J-type). You’ll write a basic disassembler in Python...
Suppose that a beq instruction resides at memory address 0x08000000 and that the rightmost 16 bits within the machine code for the beq contains the value 0x00BB. To what value (expressed in hex) would the PC be set if the zero flag=1 when the beq instruction is executed?
19 Suppose a machine has fifteen (15) general-purpose 32-bit registers How many bits must be reserved in the machine code instruction in order to address any one of these fifteen registers? (1) 1 (2) 2 (3) 3 4 (5) 5
1) We would like to design a bus system for 32 registers of 16 bits each. How many multiplexers are needed for the design? Select one: 5 16 1 4 32 2) The basic computer can be interrupted while another interrupt is being serviced. Select one: True False 3) If the Opcode bits of an instruction is 111, then the basic computer instruction type is either memory-reference or input-output. Select one: True False 4) The content of AC in the...
