A processor employs a set of bits to indicate values of portions of registers of a register file. In response to a specified instruction indicating an expected change of instruction types to be executed, the processor sets one or more of the bits and, for subsequent instructions, interprets corresponding portions of the registers as having a specified value (e.g., zero). By employing the set of bits to set the values of the register portions, rather than setting the individual portions of the registers to the specified value, the processor conserves processor resources (e.g., power) when the processor transitions between executing instructions of different types.

A source device includes a forward error correction encoder circuit to generate error correction protected blocks from video data packets. Each error correction protected block includes data words and error correction words. An encoder circuit encode X-bit words of the error correction protected blocks into Y-bit encoded words for transmission to a sink device over one or more multimedia lanes of a multimedia communication link, where X is smaller than Y.

The present invention relates to a method and encoding device for encoding a sequence of m-bit pattern words and outputting as a bit-stream a frame comprising corresponding n-bit symbols as well as a predetermined comma symbol, wherein m<n, wherein occurrences of false commas in the output bitstream are avoided. The output bitstream may further be optimized based on CID count and DC balance.

A communication method executed by a communication system including a transmission circuit and a reception circuit, the communication method includes encoding, by the transmission circuit, inputted data according to an encoding method of converting a pre-converted bit string into a bit string in which a number of consecutive bits representing a same value is equal to or less than a predetermined threshold value, transmitting a first serial signal representing the encoded data, in a first period in which a radio signal outputted from the transmission circuit is communicated wirelessly, and transmitting a second serial signal representing a bit string which includes a continuous number of consecutive bits representing a same value, in a second period in which the radio signal is not communicated wirelessly, the continuous number being greater than the threshold value, and receiving, by the reception circuit, the first serial signal and the second serial signal.

The invention relates to a invention relates to a method and decoding device for receiving an input bit-stream comprising a sequence of n-bit pattern symbols as well as a unique n-bit comma symbol for synchronization, and for generating therefrom a synchronized output comprising a sequence of m-bit pattern words, with m<n. The comma symbol allows detection of bit-skip in the input bit-stream, so that the output to be synchronized to compensate for the bit-skip. The decoding device and method of decoding are particularly simple and may be applied in devices, e.g. in a beam modulator array comprising a plurality of decoding devices, and/or in a lithography system comprising such a beam modulator array, in which space and computational resources are scarce while still providing a synchronization capability.
