Abstract
Methods and systems are described for receiving signal elements corresponding to a first group of symbols of a vector signaling codeword over a first densely-routed wire group of a multi-wire bus at a first set of multi-input comparators (MICs), receiving signal elements corresponding to a second group of symbols of the vector signaling codeword over a second densely-routed wire group of the multi-wire bus at a second set of MICs, and receiving signal elements corresponding to the first and the second groups of symbols of the vector signaling codeword at a global MIC.
Claims20
A method comprising:
- receiving signal elements corresponding to a first group of symbols of a vector signaling codeword over a first densely-routed wire group of a multi-wire bus at a first set of multi-input comparators (MICs);
- receiving signal elements corresponding to a second group of symbols of the vector signaling codeword over a second densely-routed wire group of the multi-wire bus at a second set of MICs;
- and
- receiving signal elements corresponding to the first and the second groups of symbols of the vector signaling codeword at a global MIC.
An apparatus comprising:
- a first set of multi-input comparators (MICs) connected to a first densely-routed wire group of a multi-wire bus, the first set of MICs configured to receive signal elements corresponding to a first group of symbols of a vector signaling codeword;
- a second set of MICs connected to a second densely-routed wire group of the multi-wire bus, the second set of MICs configured to receive signal elements corresponding to a second group of symbols of the vector signaling codeword;
- a global MIC connected to the first and second densely-routed wire groups configured to receive signal elements corresponding to the first and second groups of symbols of the vector signaling codeword.
