Many of the modern applications of microelectronics require
hugeamounts of computations. Despite all recent improvements in
fabrication technologies, some of these computations have to be
performed in hardware in order to meet deadlines. However,
controlling computations by software is frequently pre ferred due
to the larger flexibility. Hence, in general, modern applications
re quire a mix of software-based and hardware-based computations.
Applications using this mix can be designed with the help of
hardware/software co-design systems. Many such co-design systems
have been described so far (references can be found in this book),
but many of these are based on heuristics. In this book, Niemann
describes a co-design system which is based on sound modeling
techniques. This system has the following salient features: *
Precise cost and performance figures Design decisions for
implementing a certain function in hardware or software are based
on 'cost and performance figures for the different design alterna
tives. Hence, good designs can only be expected if these figures
are accurate. In order to achieve excellent accuracy, Niemann takes
a new approach: the cost of software implementations is derived
from the data available about the target processors and from
knowledge about the code size. the performance of software
implement at ions is computed by compiling the given function and
then using static analysis for computing worst case execution
times. the cost of hardware implementation is estimated by running
higher-Ievel synthesis tools. the performance of hardware
implementations is again computed by us ing static analysis.
