Abstract
Methods and apparatuses are described to determine subsets of vector signaling codes capable of detection by smaller sets of comparators than required to detect the full code. The resulting lower receiver complexity allows systems utilizing such subset codes to be less complex and require less power.

An apparatus comprising:
- an arithmetic unit connected to a plurality of wires of a multi-wire bus comprising at least four wires, the arithmetic unit comprising at least first and second averaging units connected to first and second pairs of wires, respectively, the first and second pairs of wires being disjoint, the first and second averaging units configured to generate first and second averaging results respectively based on signal values received on the first and second pairs of wires;
- and
- a comparator unit comprising a two-input comparator configured to receive the first and second averaging results from the arithmetic unit, and to responsively form a binary output representing a result of a comparison of the received first and second averaging results.
A method comprising:
- receiving a plurality of signals via wires of a multi-wire bus comprising at least four wires;
- generating first and second averaging results using first and second averaging units, the first and second averaging units receiving signal values from first and second pairs of wires, respectively, the first and second pairs of wires being disjoint;
- and
- forming a binary output at a comparator unit comprising a two-input comparator, the comparator unit receiving the first and second averaging results from the first and second averaging units, the binary output representing a result of a comparison of the received first and second averaging results.
