Pg. Paulin et al., EMBEDDED SOFTWARE IN REAL-TIME SIGNAL-PROCESSING SYSTEMS - APPLICATION AND ARCHITECTURE TRENDS, Proceedings of the IEEE, 85(3), 1997, pp. 419-435
This paper presents an extensive survey of trends in embedded processo
r use with an emphasis on emerging applications in wireless communicat
ion, multimedia, and general telecommunications. We demonstrate the im
portance of application-specific instruction-set processors (ASIP's) i
n high-volume, low cost applications. We also examine some of the unde
rlying trends of the applications in which embedded processors are use
d. This is followed by a description of embedded software development
tool requirements. High-performance software compilation emerges as a
key requirement. Finally specific industrial case studies of products
in MPEG, videophone, and low-cost digital signal processor (DSP) appli
cations are used to illustrate the architecture design tradeoffs, and
highlight specific tool requirements, A companion paper in this issue
[1] presents a comprehensive survey of embedded software development t
ools, focusing mostly on retargetable software compilation.
