    摘要: In a proximity communication system, transmit elements on one chip are aligned with receive elements on a second chip juxtaposed with the first chip. However, if the elements are misaligned, either statically or dynamically, the coupling between chips is degraded. The misalignment may be compensated by controllably degrading performance of the system. For example, the transmit signal strength may be increased. The bit period or the time period for biasing each bit may be increased, thereby decreasing the bandwidth. Multiple coupling elements, such as capacitors, may be ganged together, thereby decreasing the number of channels. The granularity of symbols, such as images, may be increased by decreasing the number of bits per symbol. Multiple coupling elements, such as capacitors, may be ganged together, thereby decreasing the number of channels.

    摘要: A multi-chip module (MCM) is described. This MCM includes multiple sites, where a given site in the multiple sites includes multiple chips with proximity connectors that communicate information through proximity communication within the MCM via multiple components associated with the given site. Note that the MCM includes global redundancy and local redundancy at the given site. In particular, the global redundancy involves providing one or more redundant sites in the multiple sites. Furthermore, the local redundancy involves providing one or more redundant chips in the multiple chips and one or more redundant components in the multiple components.
