What is an opcode and operand in an instruction set? In an instruction set, an opcode (operation code) is the portion of a machine language instruction that specifies the operation to be performed. It's like the verb in a sentence. On the other hand, an operand is the part of the ins...
an operand in an addition operation might be referred to as theaddendorsummand, and an operand in a multiplication operation might be called thefactorormultiplier. If multiplier is used, it typically refers to the second operand in the multiplication...

Each MIPS instruction must be submitted to the CPU in the proper 32-bit format. The operand indicates the operation and type of instruction. If the operand is 000000, it is an R-type, in which case, the instruction's purpose is indicated by the final six bits (func). Moving from sourc...

Machine code is a coputer programming language consisting of strings of zeros and ones. Computers can execute machine code directly.
instructions, potentially far away, allowing the software to continue as intended. In x86, JMP is encoded as 0xE9…0xEB, 0xFF/4 and 0xFF/5. JMP will take an operand that details the memory address to which the program counter needs to be updated to point to the correct next instruction...
A computer has a 32bit instruction word broken into fields as follows: opcode, six bit; two register fields, five bits each; and one immediate operand/register field, 16 bits. a) What is the maximum n You have been given 18 32K 16-bit SRAMs to build ...
Data:Three parallel buses are contained by the ALU, which include two input and output operand. These three buses handle the number of signals, which are the same. Opcode:When the ALU is going to perform the operation, it is described by the operation selection code what type of operation ...
