Space telemetry protocols based upon recommendations by the Consultative Committee for Space Data Systems (CCSDS) are gaining wide acceptance within the international space telemetry community. These recommendations specify a very powerful interleaved Reed-Solomon code to protect its multi-layered, datadriven protocol format. As spacecraft telemetry data rates continue to increase, the computationally intensive nature of Reed-Solomon error correction requires a high-performance solution for space telemetry acquisition systems. This paper describes the development of a single-chip deinterleaving Reed-Solomon Error Correction decoder that demonstrates low-cost error correction for CCSDS-compatible data streams. This ReedSolomon Error Correction chip, designed to operate at rates up to 300 Megabits per second (Mbps), also incorporates additional onchip features such as cumulative quality accounting, real-time quality trailer generation, and fill frame removal.
