Abstract:
Methods and apparatus relating to enhanced Data Bus Invert (EDBI) encoding for OR chained buses are described. In an embodiment, incoming data on a bus is encoded based at least in part on a determination of whether a next data value on the bus is going to transitioning from a valid value to a parked state. Other embodiments are also disclosed.
Abstract:
In an embodiment, a processor includes error correction code (ECC) circuitry to: receive a codeword comprising data bits and parity bits; generate, using a parity checking matrix H, a syndrome vector associated with the received codeword, where the parity-checking matrix H comprises a data segment comprising N data columns and a parity segment comprising K parity columns, where a total quantity of data columns in the data segment with even weight is equal to N+K-2 (K-1) +1; and detect an adjacent two bit error in the codeword based on a comparison of the syndrome vector to the parity checking matrix H. Other embodiments are described and claimed.
