We present an extensive survey of trends in embedded processor use with an emphasis on emerging applications in wireless communication, multimedia, and general telecommunications. We demonstrate the importance of application-specific instruction-set processors (ASIPs) in high-volume, low cost applications. We also examine some of the underlying trends of the applications in which embedded processors are used. 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) applications are used to illustrate the architecture design tradeoffs, and highlight specific tool requirements. A companion paper (Goosens et al., 1997) presents a comprehensive survey of embedded software development tools, focusing mostly on retargetable software compilation
