What is the size of an instruction?
Instruction length The size or length of an instruction varies widely, from as little as four bits in some microcontrollers to many hundreds of bits in some VLIW systems. Processors used in personal computers, mainframes, and supercomputers have instruction sizes between 8 and 64 bits.

The length of the one-byte instruction is This format is 2 byte long. Solution: The LSBs(least significant bits) from 0 to 3 represent R/M field that specifies another register or memory location i.e. the other operand.
What is the use of branching instructions?
The branch instructions are used to change the sequence of instruction execution. Use branch instructions to change the sequence of instruction execution.
Which of the following is the example of branch instruction?
Learn about this topic in these articles: For example, a branch instruction might be “If the result of the last ALU operation is negative, jump to location A in the program; otherwise, continue with the following instruction.” Such instructions allow…
What is the function of stack pointer in 8085?
The Stack Pointer register will hold the address of the top location of the stack. And the program counter is a register always it will hold the address of the memory location from where the next instruction for execution will have to be fetched. The complete programmer’s view of 8085 is shown in the following figure.
What is register stack explain it with example?
A stack register is a computer central processor register whose purpose is to keep track of a call stack. Some designs such as the Data General Eclipse had no dedicated register, but used a reserved hardware memory address for this function.
