Unique—and sometimes obscure—characteristics distinguish single-chip microcomputers from conventional architectures. Current examples show that no one section can be optimized at the expense of another.
Io Overview Various symbolic languages such as RTN (Register Transfer Notation) have been created to describe computer instruction sets. In general, these languages have served two of the three purposes described by Wulf [Wulf gO]. These languages serve as design tools and as vehicles for human communication. However, these languages are not executable, the… (More)

Data from a study of both static and dynamic instruction traces of popular workstation type programs for a MIPS processor is presented. The instruction traces were analyzed to extract the branch distances, and instruction sequences of 1, 2, 3, 4, and 5 instructions.
Integrated circuits having complexity levels approaching one million devices per chip (VLSI) present significant problems in the cost of design and use. There are advocates for very capable design automation techniques coupled with rapid turnaround front ends as the path to VLSI. Others advocate the use of programmable devices such as microcomputers and… (More)
