In a computer-type architecture, all facilities dedicated to the sole purpose of address processing must be considered part of the controller, not of the datapath, even if they are ALUs or registers by nature..

From Algorithms to Architectures 2.1 The goals of architecture design VLSI architecture design is concerned with deciding on the necessary hardware resources for solving problems from data and/or signal processing and with organizing their interplay in such a way as to meet target speci cations de ned by marketing. The foremost concern is to get the desired functionality right. The second priority is to meet some given performance target, often expressed in terms of data throughput or operation rate.

A third objective, of economic nature this time, is to minimize production costs. Assuming a given fabrication process, this implies minimizing circuit size and maximizing fabrication yield so as to obtain as many functioning parts per processed wafer as possible.1 Another general concern in VLSI design is energy e ciency.

Battery-operated equipment, such as hand-held cellular phones, laptop computers, digital hearing aids, etc., obviously imposes stringent limits on the acceptable power consumption. It is perhaps less evident that energy e ciency is also of interest when power gets supplied from the mains.

The reason for this is the cost of removing the heat generated by high-performance high-density ICs. While the VLSI designer is challenged to meet a given performance gure at minimum power in the former case, maximizing performance within a limited power budget is what is sought in the latter. The ability to change from one mode of operation to another in very little time, and the exibility to accommodate evolving needs and/or to upgrade to future standards are other highly desirable qualities and subsumed here under the term agility.

Last but not least, two distinct architectures are likely to di er in terms of the overall engineering e ort required to work them out in full detail and, hence also, in their respective times to market.. The problem s and m etho ds Software Code 39 Full ASCII asso ciated with m aking sure functionality is im plem ented correctly are addressed in chapter 3. Yield and cost m o dels are discussed in chapter 13 along with other business issues that relate to VLSI design and m anufacturing..
