What are the advantages of superscalar processor?
The main benefit and difference of superscalar technology versus pipelining is that it allows processors to execute more than one instruction per clock cycle with multiple pipelines.
What is distinctive about superscalar processors?
A superscalar CPU design makes a form of parallel computing called Instruction-level parallelism inside a single CPU, which allows more work to be done at the same clock rate.
What is the throughput of a superscalar processor?
This set of Computer Organization and Architecture Multiple Choice Questions & Answers (MCQs) focuses on “Superscalar Processors”. Explanation: The throughput of a processor is measured by using the number of instructions executed per second. Explanation: None.
What is superscalar processor design characteristics?
A superscalar processor is a microprocessor design for exploiting multiple instructions in one clock cycle, thus establishing an instruction-level parallelism in processors. A superscalar is a super-pipelined model where only the independent instructions are executed sequentially, without any waiting state.
What are the factors limiting the degree of superscalar design?
Available performance improvement from superscalar techniques is limited by three key areas:
- The degree of intrinsic parallelism in the instruction stream (instructions requiring the same computational resources from the CPU)
- The complexity and time cost of dependency checking logic and register renaming circuitry.
How does a superscalar processor work?
In a superscalar computer, the central processing unit (CPU) manages multiple instruction pipelines to execute several instructions concurrently during a clock cycle. This is achieved by feeding the different pipelines through a number of execution units within the processor.
What are superscalar processors explain the structure of a typical superscalar processor?
A superscalar processor is a specific type of microprocessor that uses instruction-level parallelism to help to facilitate more than one instruction executed during a clock cycle. This depends on analysis of the instructions to be carried out and the use of multiple execution units to triage these instructions.
Does pipelining improve latency?
Super pipelining improves the performance by decomposing the long latency stages (such as memory access stages) of a pipeline into several shorter stages, thereby possibly increasing the number of instructions running in parallel at each cycle.
Which of the following is not a pipeline conflicts?
3. Which of the following is not a Pipeline Conflicts? Explanation: Load Balancing is not a Pipeline Conflicts.
What are the major differences between superscalar processor and VLIW processor?
Superscalar Processor
| VLIW Architecture | Superscalar Processor |
|---|---|
| VLIW Architecture receives single multi-operation instruction. | Superscalar processor except for a traditional sequential flow of instruction but it can issue multiple instructions. |
What are the differences between superscalar and VLIW?
Superscalar and VLIW processors can both execute multiple instructions each cycle. Each employs a different instruction scheduling method to achieve multiple instruction execution. Superscalar processors schedule instructions dynamically, and VLIW processors execute statically scheduled instructions.
What are the key elements of a superscalar processor organization?
What are the key elements of a superscalar processor organization? Instructions on conditional branch Multiple stages of pipeline fetch, Pipeline decode and pipeline branch prediction logic is used by above points.
