  2. Instruction cycle - Wikipedia

    en.wikipedia.org/wiki/Instruction_cycle

    The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetchexecute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the execute stage.

    The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch-execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the execute stage.

    The green instruction can proceed to the Execute stage and then to the Write-back stage as scheduled, but the purple instruction is stalled for one cycle at the Fetch stage. The blue instruction, which was due to be fetched during cycle 3, is stalled for one cycle, as is the red instruction after it.

  5. Classic RISC pipeline - Wikipedia

    en.wikipedia.org/wiki/Classic_RISC_pipeline

    The data hazard is detected in the decode stage, and the fetch and decode stages are stalled - they are prevented from flopping their inputs and so stay in the same state for a cycle. The execute, access, and write-back stages downstream see an extra no-operation instruction (NOP) inserted between the LD and AND instructions.

  6. Central processing unit - Wikipedia

    en.wikipedia.org/wiki/Central_processing_unit

    Nearly all CPUs follow the fetch, decode and execute steps in their operation, which are collectively known as the instruction cycle. After the execution of an instruction, the entire process repeats, with the next instruction cycle normally fetching the next-in-sequence instruction because of the incremented value in the program counter. If a ...

    increment, decrement in some ISAs, saving operand fetch in trivial cases. Perform bitwise operations, e.g., taking the conjunction and disjunction of corresponding bits in a pair of registers, taking the negation of each bit in a register. Compare two values in registers (for example, to see if one is less, or if they are equal).

    I mean I can describe for you the process of sort of building and testing and validating a platform of this nature. And it's one that probably won't surprise you to learn is highly iterative.

  9. Instruction unit - Wikipedia

    en.wikipedia.org/wiki/Instruction_unit

    The instruction unit (I-unit or IU), also called, e.g., instruction fetch unit (IFU), instruction issue unit (IIU), instruction sequencing unit (ISU), in a central processing unit (CPU) is responsible for organizing program instructions to be fetched from memory, and executed, in an appropriate order, and for forwarding them to an execution unit (E-unit or EU).
