G-32-a high performance VSLI 3-D computer

A 3-D computer is characterized by sufficient speed of CPU computation, high I/O throughput, and an efficient interrupt-handling capability. The architecture of a high-performance 32-bit three-dimensional (3-D) computer, based on a custom-designed VSLI chip set is described. The G-32 consists of a single-board CPU, up to two single-board dual-bus input/output sequencers, and a memory subsystem expandable from 2 to 256 Mbytes. Up to four CPUs and four sequencers can be configured together in a multiprocessor system. The G-32 system is intended for use in real-time, time-sharing processing applications. It uses advanced high-performance CMOS gate arrays and standard cell devices. Floating-point operations have been improved with the addition of a hardware accelerator.<>
