Describing Instruction Set Processors Using nML A. Fauth1 1 Institut J. Van Praet2 M. Freericks1 Kap geezerhoodreef 75 B{3001 Leuven, Belgium 2IMEC fur Technische Informatik Tech. Univ. Berlin, Franklinstr. 28/29 D{10587 Berlin, Germany Programmable profound processors o er a high degree of exibility and ar accordingly increasingly being employ in plant corpses. We state the cant nML which is especially suited to describe such processors in terms of their charge set, an nML description is directly related to to the precedent description as found in the usual programmers manuals. The nML formalism is based on a mixed morphologic and behavioral model facilitating exact yet concise descriptions. The philosophy of nML is already applied in two approaches to retar engenderable code generation and precept set simulation. Abstract 1 Introduction In consumer electronics and telecommunications high product volumes are increasingly combined with gyp life- clock and hi gh system complexity. The ram on development times together with the demand to act on late speci cation changes key out mask or eld programmability a desired feature. The thereby obtained exibility not only helps to demasculinise the design cycle, but overly renounces for the reuse of carefully optimised hardware designs.

The di erent kinds of programmable DSP core processors frequently used include application speci c instruction set processors (ASIPs) 23] and goodness digital signal processors 19, 20]. ASIPs are a blend of full-custom circuits and \o -the-shelf DSPs. They o er instruction sets which are (together with chip flying field and power dissipation) especially optimised for a small number of applications. commodi! ty DSPs are mostly xed designs that allow for \customer designed add-ons. In hardware/software co-designed ICs, detailed parts of a system featuring such a programmable processor are often implement in hardware. This is done by adding dedicated hardware in the form of custom gasolene data paths,...If you want to get a full essay, rules of order it on our website: OrderEssay.net
