| Research Abstract |
In this research, we propose a technique for hardware implementation of protocol specifications in LOTOS.For the purpose, we define a new model called synchronous EFSMs consisting of concurrent EFSMs and a finite set of multi-redezvous indications among their subsets, and propose a conversion algorithm from a subset of LOTOS.The derived synchronous EFSMs described in VHDL can be easily implemented as a synchronous sequential circuit where all the modules corresponding to the EFSMs work synchronously with the same clock.By applying our technique to the Abracadabra protocol and a sinple network switch, it is confirmed that the derived circuit handles multi-rendezvous efficiently.
