Systematic Approach to Increase Efficiency of Execution of CHDL Simulation Programs

801

Abstract

The efficiency of execution of CHDL simulation programs in a multi-processr environment is examined in this paper. This problem is considered on two basic levels: the simulation system level and the simulation program level. The CHDL simulation systems with control graph mechanisms are considered. The OSM language is taken as an example. The algorithm of allocation of simulated architecture in a multi-processor reconfigurable system is given, illustrated with spacious examples. The allocation problems when no sufficient resources (processors and/or links) are available are discussed in details. Such a situation requires dynamic reconfiguration. Finally, conclusions are drawn and some indications for future research given.
