SIMD, SIMT, VLIW, Superscalar, Superpipeline

$(1)(4\%)$ Explain the major features of single instruction multiple data $($SIMD$)$ processors. In

other words, point out the major differences between SIMD CPU and conventional CPU. Give

a practical example of SIMD instructions, CPU, or computer.

$(2)(4\%)$ Compare the differences of thread and process. Is context switching the change of

threads or the change of process?

$(3)(4\%)$ Explain the major features of single instruction multiple threads $($SIMT$)$ processors.

Give a practical example of SIMT computer.

$(4)(4\%)$ Explain the major features of very long instruction word $($VLIW$)$ processor. Which

processor category does VLIW belong to$,$ static multiple issue or dynamic multiple issue?

$(5)(4\%)$ What is a superscalar processor? What is a superpipeline processor?
