Abstract:

The study presented in this report addresses the application of direct execution computer architecture concepts using low-cost, large-scale-integration LSI to continuous system simulation. Basic architecture schemes for direct execution systems were investigated and applied to a demonstration interactive simulation language. A dual processor direct execution system was designed and built using an LSI-11 microcomputer, a 16K x 16 dual port memory, a microprogrammed AMD 2900 bit-slice direct execution processor, and a 16 x 16 multiplier chip. The system features a distinct separation of interpretivecompiler software and simulation run execution firmware linked via the dual port. The system is demonstrated via several simulation examples including realtime control, optimization, and torpedo dynamics problems. Author
