MODULAR ERROR CORRECTION CODE CIRCUITRY

Abstract:

A modular Error Correction Code (ECC) scheme in a multi-channel IO link of an integrated circuit device is provided. The integrated circuit device may include core logic circuitry that may be configured after manufacturing. To accommodate the resulting variation, the modular ECC scheme may allow for partitioning a parity check matrix associated with the configuration of the core logic and peripheries coupled to the core logic. The parity check matrix is partitioned into smaller block matrices that is programmable. Multiple ECC modules corresponding to the block matrices are used to provide error detection and correction in the multi-channel IO link. The modular ECC scheme combined with programmable matrices (configurability) enables multi-channel IO link to be flexible to form different IO topologies.
