Abstract

This article proposes that subword paraiielism --prallel computation on lower precisicm data packed into a word--is an efficient and effective solution for accelerat- ing media processing. As an example, t describes MAX-2, a very lean. RISCdike et of media acceleration primitives included in the 64-bit PA-R1SC 2.0 architecture. Because MAX-2 strives 1o be a minhnal set of instree~ dons, the article dbcusses both instructions included and excluded. Several examples filustrate the use of MAX-2 instructions, which provide subword paralleiism in a word oriented general-purpose processor at essentially no incremental cost
