What is instruction execution?
The definition of instruction execution is the process of carrying out an instruction by a computer. This is what was formerly known as a command execution in DOS.
Does an interrupt actually interrupt the execution of an instruction at any time during the instruction execution cycle?
Yes , an interrupt actually interrupt the execution of an instruction at any time during the instruction execution cycle.AS there the execution takes in 4 t cycles and t3 to take up the data and the 4th cycle for execution,if there is an interruption then there will be an interruption any time in any instruction execution cycle.
What is instruction execution time In what unit is a computer speed measured?
about instruction execution time
What is an instruction phase together with the execution phase called?
The instruction phase together with the execution phase is called a "Machine Cycle".
What are the two types of instruction execution?
The two types of instruction execution are pipelining and not pipelining. Pipelining involves breaking down instruction execution into multiple stages that can overlap, improving efficiency. Not pipelining involves executing one instruction at a time without overlapping stages.
What are the different phases in instruction execution explain?
Instruction execution can be divided into five phases. These are Phase-I: INSTRUCTION FETCH (IF) II: INSTRUCTION DECODE & OPERAND FETCH (ID) III: EXECUTION (EX) V: MEMORY OPERATION (MEM) V: WRITE BACK (WB) - Regards, Subhradip Das
What will be the contents of PC after the execution of RST 4 Instruction?
20H
What is instruction cycle with interrupts?
The instruction cycle is the basic operation cycle in a computer. This is what will take in data, process it and execute as required.
How program and data memory fetches can be overlapped in a Harvard architecture?
In Harvard architecture, the program memory space is distinct from data memory space. Such architecture requiring two connections. It can perform instruction fetch ( from program memory ) and data memory fetch simultaneously , by adopting a pipelined instruction execution approach, as shown below. A typical instruction execution consists of performing Fetch instruction, Decode instruction, Fetch operands, execution operation , store results. Then, by adopting a pipelined approach, which is possible in Harvard architecture, it is evident that the instruction throughput increases by overlapping. It is simple to imagine that in the above case, if all the above states are executed "one after the other" , the execution time of the instruction will be longer than when it is pipelined.

What action is taken when the processor under execution is interrupted by TRAP in 8085MPU?
Processor serves the interrupt request after completing the execution of the current instruction.
Conditional results after execution of an instruction in a microprocess is stored in?
Flag register part of psw
