摘要： A decoder includes a transport engine configured to receive programs and extract timing information and timestamps embedded in the programs. An adder is configured to add a set of timing offsets to the sets of timing information to adjust the timing information from a first time basis to a second time basis. Sums of the timing offsets and the timing information are referred to the mapped-timing information. A correction engine is configured to update the timing offsets as timing information is encountered in the programs, and an offset register is configured to: receive the timing offsets, store the timing offsets, and transfer the timing offsets to the adder. The adder is also configured to add the timing offsets to the timestamps to adjust the time basis of the timestamps from the first time basis to the second time basis. A program is decoder configured to receive the adjusted timestamps to decode the programs.

摘要： An active pixel CMOS image sensor implements full frame digital correlated double sampling (CDS) with global shutter where all the pixels in the image sensor are reset at substantially the same time and all the pixels in the image sensor integrate incident light at substantially the same time and for substantially the same time duration and correlated double sampling cancellation is performed in the digital domain. In one embodiment, the image sensing device includes an array of light sensing elements, a timing and control circuit and analog-to-digital converters. The timing and control circuit is operative to reset the light sensing elements in the array and to control the array of light sensing elements to integrate incident light. The pixel reset values are cancelled from the corresponding light dependent pixel values for each of the light sensing elements to generate correlated double sampling (CDS) corrected digital output pixel values.

摘要： An image sensor including an array of pixel elements is operated according to two operation modes to modulate the conversion gain of the pixel to operate the image sensor based on the impinging light conditions. More specifically, an image sensor pixel element is operated in a high conversion gain mode for low light conditions and in a low conversion gain mode for bright light conditions. The low conversion gain mode implements charge sharing between the floating diffusion and the photodiode. The low conversion gain mode further implements partial reset where the photodiode and the floating diffusion are reset to the same potential and to a potential slightly less than the pinning voltage of the photodiode.

摘要： A deinterleaver for performing high-speed multi-channel forward error correction using external SDRAM is provided. According to one exemplary aspect, the deinterleaver performs both read and write accesses to the SDRAM that are burst-oriented by hiding active and precharge cycles in order to achieve high data rate operations. The data bus length of the SDRAM is designed to be twice the deinterleaving symbol size thereby allowing bandwidth to be increased. The deinterleaver accesses data in the SDRAM as read blocks and write blocks. Each block includes a predetermined number of data words to be interleaved/deinterleaved. The ACTIVE command for one block is issued when a preceding block is being processed. Data in one read/write block has the same row address within the same bank of the SDRAM.

摘要： A method and system for extending the range of a security token allow a system to have a security token be utilized remotely from the system that will receive information and signals from that security token. A remote token extender can interface with a security token (such as an identity (or ID) token), configure the signals and information associated with that security token into a format for transmission across a selected media (such as a network), and transmit those signals and information across that media. At the receiving end, a local token extender can reconstitute those signals and information for use by a complementary device (such as an ID card reader) at the local system.
