Hamming Code - A bit encoding used to detect and correct SBEs (single bit errors) and to detect MBEs (multi-bit errors) for memory devices which may be subject to SEUs.
Hard Real-Time - A service or set of services which are required to meet their deadlines relative to request frequency - if such deadlines are missed, there is not only no utility in continuing the service, but in fact the consequences to the system are considered fatal or critical.
Harmonic - When the relative periods of services are all common multiples of each other - this characteristic can yield cases where the CPU resource can be deterministically scheduled to full utility.
Harvard Architecture - a core CPU architecture which splits the memory hierarchy into separate instruction and data streams - typically including an L1 instruction cache which is independent of an L1 data cache.
