Abstract

The data path of an architecture defines the alignment of processing elements. It realizes a certain functionality which fulfills a given throughput constraints. There exit always different possibilities to realize a defined functionality. Here we describe the individual steps to the design of individual components, again tailored for communications systems as shown in Fig. 4.1. Note, there is a difference of a data path for individual components and the data path for processors. The data path of a general purpose processor has the task to be as flexible as possible, thus arithmetics units are used with large bit width to provide a high flexibility, e.g. 32 bit or 64 bit. For dedicated hardware design the data path and thus the computational units are optimized with respect to the given algorithm to be processed. The steps to derive a dedicated data path are:
