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 telephone exchange processors o er a high degree of exibility and ar accordingly increasingly being utilize in embed outlines. We state the cant nML which is especially suited to describe much(prenominal) processors in terms of their charge set, an nML description is directly related to to the precedent description as found in the regular programmers manuals. The nML formalism is based on a mixed morphological and behavioral model facilitating exact yet concise descriptions. The doctrine of nML is already applied in two approaches to retar cohereable code coevals and precept set simulation. Abstract 1 Introduction In consumer electronics and telecommunications high product volumes are increasingly combined with m ulct life- generation and high system complexity. The ram on development times together with the demand to act on late speci cation changes pull 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 good 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 nation and power dissipation) especia lly optimised for a small number of applicat! ions. trade good 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 enforced 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
