When an instruction is executed in a programm what happens in the processor memory?
Swapnajoshi
All the programming instructions whcih are basically in the assembly code has the corresponding hexadecimal code.the microprocessor understand or interprets what this code is and based on that it performs operation
for eg HLT which had hexcode 76
the microprocessor understands76 as tha halt instruction and based on that it halts or terminates the program

∙ 14y agoWhen an instruction is decoded,the processor will understand what process it has to do.If it requires some data it will read the data from memory.If the instruction is to store some data to memory,it will store it.

What happens when halt instruction is executed?
The processor stops and goes to the halt state. If an interrupt occurs, it responds and then continues execution.
What happens when MUL CH instruction is executed?
MUL is not an 8085 instruction.
What happens when branch instruction comes in 8086?
When a branch (or "jump") instruction is executed, the condition codes bits (in the flag register) determine whether or not the Program Counter (PC register) is changed to the Effective Address specified by the instruction; if not, then the PC is unchanged.
What happens when a PUSH instruction is executed?
The value being pushed (push [value]) is placed on the top of the stack (esp) and the size of the value is added to esp.
What happens when POP H instruction is executed in 8085?
The POP H instruction in the 8085 copies the top of stack to the HL register and then increments the stack pointer by 2. In C pseudo code, the sequence is L = *(SP++); H = *(SP++);
What happens after the microprocessor completes an instruction?
It fetches the next instruction.
When the microprocessor completes an instruction what happens?
it goes to queue for next instruction
What happens to a deathrow inmate after he is executed?
They die.
What happens if you harm the guru granth sahib?
You get executed by the Sikhs
What happens when a computer is over used?
Freezing occur when the processor is heated.
If clock speed increases then what happens to processor speed?
Th clock speed is the processor speed. It is simply the amout of operations the processor can do per second. However if the processor has multiple cores, it will be as fast as number of cores * clock speed. Note that the processor speed is not the overall computer speed.
What happens to ip after completion of fetch of instruction code?
IP is incremented after fetch of instruction opcode. Specifically, IP is incremented by the number of opcode bytes.
