Summary: 
This paper presents a Reconfigurable Machine (RM). capable of efficiently implementing a wide range of computationlly complex algorithms. Its highly flexble architecture combining FPGA's with RAM's supports a wide range of applications. Since its "gate-level programmability" allows us to implement various kinds of parallel processing techniques, RM provides a perfomance comparable to exising "special-purpose" engines. The in-circuit reconfiguration capability of FPGA's is used to reload several kinds of configuration data during power on. Thus, RM behaves itself like a general-purpose computer applicable to various kinds of applications by loading programs. A Reconfigurable Machine-(RM-) has been built as the first prototype incorporating five FPGA's and four SRAM memory banks. RM- has been applied to a multiple-delay Logic Simulator (LSIM). Employing pipeline architecture, LSIM has achieved a perfomance of l million gate events per second at 4MHz. The concept of RM is the best solution to the trade-offs between general-purpose machines and special-purpose ones. RM will be a hardware platform accelerating a wide range of applications, also offering an interesting problem in high-level synthesis.
