What else can I help you with?
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 part of the processor indicates which machine instruction in next in line for execution?
The part of the processor that indicates which machine instruction is next in line for execution is called the Program Counter (PC). The Program Counter holds the memory address of the next instruction to be fetched and executed. After the current instruction is executed, the PC is updated to point to the subsequent instruction, ensuring the sequential flow of execution in a program.
Which register deals with sequencing the execution of instructions?
The register that deals with sequencing the execution of instructions is the Program Counter (PC). The PC holds the address of the next instruction to be executed in the program sequence. As each instruction is fetched and executed, the PC is updated to point to the subsequent instruction, ensuring the correct order of execution.
What is the next step of CPU instruction?
The next step of CPU instruction typically involves the execution phase, where the CPU carries out the operation defined by the instruction. This follows the instruction fetch and decode stages, where the instruction is retrieved from memory and translated into a form the CPU can understand. During execution, the CPU performs arithmetic, logic, or control operations, often interacting with registers and memory to process data. After execution, the CPU will move to the next instruction in sequence, continuing the cycle.
What will be the contents of PC after the execution of RST 4 Instruction?
20H
How do you implement instruction level parallelism?
Instruction Level Parallelism (ILP) can be implemented through techniques such as pipelining, superscalar architecture, and out-of-order execution. Pipelining allows multiple instruction stages to be processed simultaneously, while superscalar architectures enable multiple instruction executions per clock cycle. Out-of-order execution rearranges instruction execution to optimize resource use and minimize stalls. Compilers can also enhance ILP by reordering instructions and identifying independent operations to maximize parallel execution opportunities.
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.
What is fetch execution?
Fetch execution refers to the process in computer architecture where the instruction fetch stage retrieves an instruction from memory to be executed by the CPU. This is typically the first step in the instruction cycle, where the program counter identifies the memory address of the next instruction to be fetched. Once fetched, the instruction is decoded and then executed, enabling the CPU to perform tasks as dictated by the program. Efficient fetch execution is crucial for overall system performance, as it impacts how quickly instructions can be processed.
