PROTEUS: programmable hardware for telecommunication systems
Nobuhiro Ohta, Hiroshi Nakada, Koji Yamada, Akihiro Tsutsui, Toshiaki Miyazaki · 2002
This paper discusses a new architecture for programmable hardware targeted at high-speed digital telecommunication systems and describes a preliminary design. The basic architecture of the programmable hardware is proposed based on the characteristics of functions and an analysis of logic used in actual communication subsystems performing high-speed bit level operations. The proposed architecture, called PROTEUS, includes a pipeline structure of logic and latch groups, and a 2-stage logic block structure that consists of small LUTs and wide gates. The design strategy of a prototype chip and the CAD techniques used to achieve the required performance are also discussed.>
