摘要

介绍了Unisys/AT&T通用处理元件(GPPE)模块。GPPE基于下一代精简指令集计算机(RISC)微处理器技术，结合了32b指令集架构(ISA)和33mhz操作。使用商业ISA和开放架构可以在单宽度SEM-E模块上实现最具成本效益、功能齐全、军事化的设计。GPPE的其他特性包括多层数据安全机制和保护机密数据的广泛特性。GPPE上可用的6mb SRAM和512kb EEPROM符合大型RISC寻址空间和实时操作系统要求。提供联合综合航空电子工作组两级维护概念的支持。

A high performance general purpose processing element for avionic applications

The Unisys/AT&T General Purpose Processing Element (GPPE) module is described. The GPPE, which is based upon next-generation reduced instruction set computer (RISC) microprocessor technology, combines the 32-b instruction set architecture (ISA) and 33-MHz operation. Using a commercial ISA and open architecture results in the most cost-effective, full-featured, militarized design available on a single-width SEM-E module. Other GPPE features include a multilayer data security mechanism and extensive features to protect classified data. The 6 Mbytes of SRAM and 512 kbytes of EEPROM available on the GPPE are consistent with large RISC addressing spaces and real-time operating system requirements. Support of the Joint Integrated Avionics Working Group two-level maintenance concepts is provided.<>
