The RISC processor module for FASTBUS computation applications. Final technical report
The FASTBUS system specification for high-energy physics and other data-system applications anticipates the use of multiple, high-performance processor modules for data control and event reduction associated with experiments in the physical sciences. Existing processor designs will be unable to cope with the projected data-reduction and event-handling requirements of the complex experiments planned for the next generation of particle accelerators. Data-handling strategies for experimental physics are evolving from systems based upon a single central computer to those with arrays of high-speed, sophisticated, front-end processing elements. The advent of accelerators such as LEP and LHC, and beyond, is forcing the architecture of these processors toward the simpler RISC designs to enhance both speed and the software-development issue. This report describes the prototype development of a FASTBUS RISC Processor Module (FRPM) for use as a standard processing element in FASTBUS data-acquisition systems under a Phase II SBIR grant through the U.S. Department of Energy, Division of Energy Research. The FRPM hosts a reduced instruction set computer--the SPARCengine-2 by Sun Microcomputer Systems, Inc.--capable of executing 4.2 million floating point instructions per second with a clock of up to 40 MHz. The prototype FRPM supports a port to the FASTBUS crate segment by way of a standard-logic interface. The FRPM processor operates under a commercially available real-time operating system, and application software can be developed on workstation and mainframe computer systems. We further cover the chronology of the Phase II work, a discussion of the objectives, and our experiences with an ASIC manufacturer in attempting to complete the fabrication of a chip implementing the FASTBUS Master Interface (FMI).
