Show 107 as possible. This also will require an extensive effort i.a the comparison of past and projected future implementations of both the SLA and FPL. The capability already exists to compile to SIPPLDt., CD' or Computervision External Database Format. Possible extensions in this area are to compile to CALMA GDS-II· format or Applicon format. It is felt that this type of extension is not necessary, given that many outlets for CIF already exist. The capability to generate PPL programs in Computervision· External Database Fonnat was added primarily to bypass the ClF to Computerv1sion translator stage required at the University of Utah. Some effort should be made to compare alternate compi1at1on algorithms. Perhaps some rather startling gains in circuit size and performance can be gained by going to another .global organizational strategy and implementing a complex PPL signal router. PPL program compaction may perhaps also be achieved by 1) input replication, 2) inter-state path length minimization, or 3) cotput replication and gating. There are probably many other algori:tbmic methods for producing optimized PPL programs from the compiler. Much remains to be explored in the domain of automated speed-independent systems design. Work must be done on improving the representation, simulation and compilation of. cont-rol-units. to integrated circuits. Further, the speed-independent datapath domain remains unexplored at present. Both must be explored in order to construct useful CAD tools for speed-independent systems design. |
