A hardware-command-decoding application-specific integrated circuit (HCD ASIC) is designed to decode digital command signals transmitted from a ground station to a spacecraft (uplink commands). Implemented in the ASIC is a portion of the spacecraft uplinkprotocol specified in the widely used Consultative Committee for Space Data Systems (CCSDS) international standard. A terrestrial version might be useful, for example, in decoding digital command signals for a mobile robot. The HCD ASIC performs functions that previously required several different circuits, while taking up less room and consuming less power. Implemented on a single silicon-based chip in a 256-pin package, this ASIC resists both permanent damage and single-event upsets (bit-flips) produced by ionizing radiation. Tested ASICs are available to users.
