200-ps Interchip-Delay Field-Programmable MCM for Telecommunications

概要

論文の詳細を見る
We have developed a Field-Programmable Multi-Chip Module (FPMCM) whose component is the telecommunication-oriented FPGAs, called PROTEUS. The module consists of 3 x 3 PROTEUS FPGAs and its size is 114mm square. Each PROTEUS chip is mounted on the MCM substrate using Tape Automated Bonding (TAB) technology so as to minimize the size of the MCM and the production cost. The interconnection topolgy among the FPGAs is a simple mesh. However, the connection can be changed logically, because PROTEUS itself has a special inter-I/O bypass resource in it. Using this mechanism, the interchip connection delay can be reduced without sacrificing the flexibility, compared to the previous FPMCM implementation using some other interconnection switches which often have a large propagation delay. The inter chip connection delay is 200ps. We have also developed a rapid prototyping system comprising several MCMs, and implemented telecommunication circuits in it.
