Abstract
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.<>
