摘要： A video signal processing system includes a memory for holding digital data, input and output channel circuitry for reading data from and writing data to the memory and processing circuits for processing data read from the memory to produce data to be written to the memory. Each of the input and output channels produces two types of memory request signals, a normal request signal and an urgent request signal. The normal request signal is produced to gain access to the data in the memory for normal read and wire operations. The urgent request signal is produced to access the memory when the processing circuitry is in a paused state waiting either to obtain data from the input channel or to provide data to the output channel. The normal read and write request signals are handled with substantially equal priority by first scheduling circuitry. The urgent request signals are handled by second scheduling circuits according to a fixed priority scheme. The use of the second scheduling circuitry disables the first scheduling circuitry.

摘要： Digital image data is encoded using a variable-length code which is described by a group of parameter values. Each parameter value describes a set of code values; each code value corresponds to a possible value of the data which is to be encoded. When the data is encoded, the parameter values are appended to the encoded data. A decoder stores the parameter values into a memory and then combines data values derived from the encoded data with parameter values from the memory to generate decoded data values. Each code word includes a prefix which indicates a number of successive parameter values which are to be summed, and a population index which is to be added to the summed parameter values to produce a decoded data value.

摘要： A video signal processor includes a stored-program controller which concurrently reads two instruction values from a program memory during each instruction cycle. The next instruction used by the video signal processor is selected from between these two values. If the current instruction indicates a conditional branch operation, the value of one of a plurality of conditions internal to the video signal processor determines which of these two instructions is selected. Otherwise, a value provided by the current instruction itself determines which of the two instructions is selected. This configuration of the stored program controller implements a conditional branch facility in which there is no delay in fetching an instruction for either value of the selected condition.
