Architectures and Programmable Logic Devices

1. ArchitecturesandProgrammable Logic Devices

2. Abstract This section will begin with the review of different programmable logic types available for military and aerospace systems. These include PALs, PLAs, PROMs, CPLDs, and FPGAs. Device architectures will be discussed and compared with emphasis given to those architectures used in production systems such as Actel's antifuse devices, UTMC's UT22VP10 PAL, and Xilinx XQR4000XL and Virtex series devices. An introduction will be given to architectures that are being developed for military and aerospace systems such as the AT6010, the Quicklogic-UTMC developments, the MRC Orion, and the Actel ProASIC series. Radiation considerations will be summarized for different architectures and device technologies.
