What is the basic working principle of VLIW processor?
VLIW Architecture – Basic Principles These processors contain multiple functional units, fetch from the instruction cache a Very-Long Instruction Word containing several primitive instructions, and dispatch the entire VLIW for parallel execution.
What is superscalar processor and how it is different from VLIW processor?
A superscalar processor is invented to produce an execution cost of higher than one instruction per clock cycle for an individual sequential program….Superscalar Processor.
VLIW Architecture | Superscalar Processor |
---|---|
VLIW is used for static scheduling. | Superscalar is used for dynamic scheduling. |
What is the basic difference between superscalar and VLIW computers?
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 is the advantage of using VLIW instruction in Intel IA 64?
Advantages of VLIW are: Performance similar to CISC and RISC. Reduced hardware complexity over a superscalar implementation. Uses instruction level parallelism to the fullest.
What is the important feature of VLIW?
Explanation: It is the architecture designed to perform multiple operations in parallel. Explanation: ILP stands for Instruction Level Parallelism. Explanation: The Pipe-lining and super-scalar architectures involved the usage of complex hardware circuits for the implementation.
Do VLIW processors perform better than CISC processors?
A poor VLIW compiler will have a much greater negative impact on performance than would a poor RISC or CISC compiler. But even with the best compilers, there are limits to how much parallelism a VLIW processor can exploit. A good RISC or CISC design might do just as well with the software that most users run.
What is a VLIW compiler?
The compiler prearranges the bundles so the VLIW chip can quickly execute the instructions in parallel, freeing the microprocessor from having to perform the complex and continual runtime analysis that superscalar RISC and CISC chips must do.
Is VLIW the new standard for microprocessor design?
For one thing, Transmeta’s patent disclosures had tipped the secretive firm’s hand more than a year ago. But beyond that, VLIW has become the prevailing philosophy of microprocessor design, eclipsing older approaches such as RISC and complex instruction set computing (CISC).
What are the common causes of programmable logic controller failure?
Common Causes of Programmable Logic Controller Failure. 1 Input/Output Modules and Field Devices. In four out of five cases where a PLC fails, the problem comes down to one of the following three factors: 2 Ground Integrity. 3 Power Supply Failure. 4 Electrical Noise Interference. 5 Loss of Network Communication.
