High Performance Embedded Computing (HPEC) combines the latest processor and interconnect technologies with infrastructures such as OpenVPX and standard software components to allow military programs to pack more computing power into smaller size, weight and power (SWaP) for SIGINT, radar, EW, and many other applications. The drive toward Modular Open Systems Architectures (MOSA) is at the heart of Abaco Systems selection of technologies, and this paper examines how this can positively impact programs.
