Abstract: A system-on-chip (SoC) architecture includes a plurality of blocks, each including a power control module to selectively control the power dissipated by the bloc. For each block, a power register is provided to receive power control instructions to selectively control the respective power control module. The system also includes a power control unit for writing respective power control instructions into the power control registers of the blocks, whereby the power dissipated is controlled individually and independently for each block under the centralized control of the power control unit. For each block, a power status register is also provided to receive status information concerning power control within the respective block. The power control unit reads the status instructions from such power status registers.

Abstract: Digital video signals, such as the signals generated by an image sensor in a Bayer format, are converted into an encoded format. In the Bayer format, the pixels of each line are alternately coded with two colors, and then converted into the encoded format. In the encoded format, the pixels of the digital video signals are reordered into sets of adjacent pixels, such that the sets group pixels coded with the same color. The encoded signal data results in a reduced switching activity when transmitted over a bus.

Abstract: A processor is provided with a set of instructions formed, in general, of an operation section and an operand section. For at least one of the instructions, the operand section represents operation control signals of the processor. In this way, an extension of the set of instructions can be achieved for tailoring the set of instructions to the user's own requirements. Consequently, the processor control unit should be capable of coupling its outputs to its inputs upon receiving one such instruction, thereby to transfer such internal operation control signals without interpretation.

Abstract: A pipeline structure is provided for use in a digital system. The pipeline structure includes stages arranged in a sequence from a first stage for receiving an input of the pipeline structure to a last stage for providing an output of the pipeline structure. At least one intermediate stage is interposed between the first stage and the last stage. The pipeline structure also includes a phase shifting circuit for generating at least one local clock signal for controlling the at least one intermediate stage. The first stage and the last stage are controlled by a main clock signal, the at least one local clock signal is generated from the main clock signal, and the main clock signal and the at least one local clock signal are out of phase. Also provided is a method of operating a pipeline structure that includes stages arranged in a sequence.
