    摘要: A single-instruction multiple-data (SIMD) processor (10) that incorporates features for horizontal scaling of video data. The processor (10) has a data input register (11) that is operable to store input data word in sequential locations in the data input register (11) and transfer the input data words to an array of processing elements. The processor (10) also has an output data register (16) operable to receive data output words from the array of processing elements and to output said data output words from sequential locations of said output data array. An input skip signal input to the processor causes a sequential data write operation to skip a location of the input data register while an output skip signal to the processor causes a sequential data read operation to skip a location of the output data register.

    摘要: A television receiving system includes a digital unit, which has at least one single-instruction multiple-data processor, especially suitable for television processing. The processor receives data samples fo each horizontal line word-serially, but processes the line in parallel. The processor has input, computational, and output layers that operate concurrently. Internal register files emulate line memory to eliminate the need for external line memories. The processor may be programmed with various improved definition television tasks, downloaded to it from a host development system. Field memories and multiplexers control the data flow so that a still picture may be displayed.

    摘要: The invention provides an encoder for subjecting an input signal to the orthogonal transform for band compression and encoding. The encoder has a sample and hold circuit which samples the input signal at a sampling frequency three times that of the input signal, and an orthogonal transform unit which subjects the sampled signal to the orthogonal transform using as a coefficient an orthogonal matrix function of the order of 3n (where n is an integer of 2 or more) having as a minor matrix an orthogonal matrix of the order of 3: ##EQU1## having given numbers a, b and c as matrix elements. By maintaining the sampling frequency low, the frequency components of the input signal may be concentrated in a small number of transform outputs without causing an increase in the amount of data to be processed, without using a multiplier and without requiring an increase in the processing speed. The input signal is thus effectively band compressed and encoded.
