Abstract

Improvements in semiconductor integration density and the resulting problem of having to manage designs of increasing complexity is an old one, but still current. The new challenge lies in a new level of architecture heterogeneity, e.g. mixing hard-wired digital circuits with software programmed signal processors on one die. Hence, we are moving by one level of abstraction from semi-custom standard-cells to semi-custom 'block cells'. This results in a new dimension in the gap between algorithm/system design and architecture/circuit design, not addressed by any tools sufficiently yet today. This paper presents a method of analyzing the problem by orthogonalizing algorithms into data transfer and data manipulation, and carrying this over to the control and I/O design as well. This approach might be a promising basis for flexibly mapping the algorithms onto future 'block cell' designs, and furthermore for designing new system simulation tools which allow for tools to be integrated for a flexible mapping of algorithms onto various different hardware architecture domains.
