    Detectors in High-Energy Physics (HEP) have increased tremendously in accuracy, speed and integration. Consequently HEP experiments are confronted with an immense amount of data to be read out, processed and stored. Originally low-level processing has been accomplished in hardware, while more elaborate algorithms have been executed on large computing farms. Field-Programmable Gate Arrays (FPGAs) meet HEP's need for ever higher real-time processing performance by providing programmable yet fast digital logic resources. With the fast move from HEP Digital Signal Processing (DSPing) applications into the domain of FPGAs, related design tools are crucial to realise the potential performance gains. This work reviews Hardware Description Languages (HDLs) in respect to the special needs present in the HEP digital hardware design process. It is especially concerned with the question, how features outside the scope of mainstream digital hardware design can be implemented efficiently into HDLs. It will argue that functional languages are especially suitable for implementation of domain-specific languages, including HDLs. Casestudies examining the implementation complexity of HEP-specific language extensions to the functional HDCaml HDL will prove the viability of the suggested approach

    Adoption of an aggressive computer science research and technology program within NASA will: (1) enable new mission capabilities such as autonomous spacecraft, reliability and self-repair, and low-bandwidth intelligent Earth sensing; (2) lower manpower requirements, especially in the areas of Space Shuttle operations, by making fuller use of control center automation, technical support, and internal utilization of state-of-the-art computer techniques; (3) reduce project costs via improved software verification, software engineering, enhanced scientist/engineer productivity, and increased managerial effectiveness; and (4) significantly improve internal operations within NASA with electronic mail, managerial computer aids, an automated bureaucracy and uniform program operating plans
