A hybrid computer that comprises a sequential processor, a single instruction massively parallel (SIMD) processor, and shared memory module that is shared between the sequential processor and the SIMD processor.

Hybrid processor

NAND-based content addressable memory is provided with a memory cell including two programmable resistive elements, such as memristors. These memory cells can be used to provide a programmable resistive address decoder. Such decoders can improve computer hardware performance in various ways: 1) improved translation lookaside buffers, 2) improved cache memory, and 3) by eliminating physical addresses entirely.

Resistive address decoder and virtually addressed memory

The present invention provides a buffer architecture and latency reduction mechanism for buffering uncompressed/compressed information. This combination provides for a proficient division of the encoding task and quicker through-put time. The invention teaches a single chip digital signal processing device for real time video/audio compression comprising a plurality of processors, including a video input processor, a motion estimation processor, a digital signal processor, and a bitstream processor, wherein processing and transfer of the signals within the device is done in a macroblock-by-macroblock manner. The device can include a multiplexing processor that is comprised of a storage unit which buffers a compressed video bitstream and a processor which retrieves the compressed video bitstream from the storage unit and produces a multiplexed data stream whereby the compressed video bitstream is processed in a pipeline manner.

Video encoding and video/audio/data multiplexing device

An apparatus is disclosed for performing real time video/audio encoding on a single chip. Within the single chip, a video encoder generates encoded video data from uncompressed video data and an audio encoder generates encoded audio data from uncompressed audio data. A mux processor within the single chip generates an output stream of encoded data from the encoded video data and the encoded audio data.
