Prototyping the DLX microprocessor
Barry S. Fagin, Pichet Chintrakulchai · 2003
The prototyping of a functioning DLX microprocessor, based on the 32-b instruction set architecture developed by D. Patterson and J. Hennessy (in Computer Architecture: A Quantitative Approach, 1990), is described. This architecture is an emerging academic standard but has yet to be successfully prototyped. An implementation of DLX as a 12-in*15-in two-layer circuit board, containing 59 chips and running on a 2-MHz clock, is described. The execution of DLX programs and the problems encountered are discussed.>
