What do you mean by VLIW architecture?

Very long instruction word
Very long instruction word (VLIW) refers to instruction set architectures designed to exploit instruction level parallelism (ILP).

Is VLIW compiler based architecture?

VLIW has been described as a natural successor to RISC, because it moves complexity from the hardware to the compiler, allowing simpler, faster processors. The instruction set for a VLIW architecture tends to consist of simple instructions (RISC-like).

What are the goals related to VLIW architecture?

The main goal of VLIW is to remove the complicated instruction scheduling and parallel dispatch that appears in most modern microprocessors. A VLIW processor should be quicker and less costly than a comparable RISC chip.

What are the characteristics of VLIW?

A VLIW has multiple functional units, each handling one instruction from the pack. Every single instruction in a pack gets executed in lockstep. The instructions contained in a pack are statically aligned. They are directly fed into the functional units at run time.

What is VLIW in DSP?

Very Long Instruction Word (VLIW) architecture in P-DSPs (programmable DSP) increases the number of instructions that are processed per cycle. It is a concatenation of several short instructions and requires multiple execution units running in parallel, to carry out the instructions in a single cycle.

What are the pros and cons of VLIW architecture?

VLIW has both advantages and disadvantages. The main advantage is the saving in hardware — the compiler now decides what can be executed in parallel, and the hardware just does it. There is no need to check for dependencies or decide on scheduling — the compiler has already resolved these issues.

What are the advantages and disadvantages of VLIW architecture?

Is VLIW a MIMD?

The VLIW architecture follows _____ approach to achieve parallelism. Explanation: The MIMD stands for Multiple Instructions Multiple Data. Explanation: The above mentioned instruction is a complex 48 bit instruction used to perform operations on floating numbers.

What are VLIW machines?

Very long instruction word (VLIW) describes a computer processing architecture in which a language compiler or pre-processor breaks program instruction down into basic operations that can be performed by the processor in parallel (that is, at the same time).

Is VLIW a MIMD architecture?

VLIW stands for? Explanation: It is the architecture designed to perform multiple operations in parallel. Explanation: ILP stands for Instruction Level Parallelism. Explanation: The MIMD stands for Multiple Instructions Multiple Data.
