Abstract: A high speed but power-efficient electronic communications protocol may comprise dual simplex links, each operating in a differential high-speed mode and each capable of a low-speed signaling mode. When both links operate in high speed mode, signaling is performed in-band, with signals embedded as metadata attached to transmitted packets. When one of the links is put into a low-power mode, the return-path signaling may be performed on the two wires previously used for high-speed transmissions. One wire may be used for flow control or other signaling, while the other wire may be used for a wake command, which may initiate the low-power mode to be elevated to a high-speed mode. Multiple lanes may be organized to operate in parallel for each link, allowing for a very high speed communications protocol that may be easily switched into and out of a low-power state without additional sideband wiring.

A self-contained vehicle platform or chassis incorporating substantially all of the functional systems, subsystems and components (e.g., mechanical, electrical, structural, etc.) necessary for an operative vehicle. Functional components may include at least energy storage/conversion, propulsion, suspension and wheels, steering, crash protection, and braking systems.

Abstract: A method is described for encoding N variables onto less than 2N channels by forming a respective signal for each of the channels by combining inverted and/or non inverted forms of the variables, such that, each of the N variables is balanced across the channels, and, combination on any particular channel is not the polar opposite of a combination on any other channel.

Abstract: A compressed instruction format for a VLIW processor allows greater efficiency in use of cache and memory. Instructions are byte aligned and variable length. Branch targets are uncompressed. Format bits specify how many issue slots are used in a following instruction. NOPS are not stored in memory. Individual operations are compressed according to features such as whether they are resultless, guarded, short, zeroary, unary, or binary. Instructions are stored in compressed form in memory and in cache. Instructions are decompressed on the fly after being read out from cache.

Abstract: A receiver is provided which quickly and efficiently recognizes signals by including with the receiver a resolving circuit which is coupled to a signal generation circuit which provides a differential current. The resolving circuit is coupled to a latching circuit. The resolving circuit can operate with supply voltage levels as low as one threshold voltage. Also, the signal setup and hold times are inherently vary small due to the high intrinsic bandwidth of the receiver. Other advantages include reduced power consumption, high speed operation, good rejection of input noise and power supply noise, ability to resolve small (e.g., 1.0 mVolt) voltage differences, reduced capacitive loading, and the ability to function with a variety of types of drivers, including HSTL, DTL and PECL.
