摘要： A space vector data path for integrating SIMD scheme into a general-purpose programmable processor. The programmable processor uses a mode field in each instruction to specify, for each instruction, whether an operand is processed in either one of vector or scalar modes. The programmable processor also has a plurality of sub-processing units for receiving the operand and, responsive to an instruction as specified by the mode field in each instruction, for processing the operand in either one of the vector or scalar modes, wherein the vector mode indicates to the plurality of sub-processing units that there are a plurality of elements within the operand and the scalar mode indicates to the plurality of sub-processing units that there is but one element within the operand. For the vector mode, each element is processed by one of the sub-processing units concurrently to generate a vector result. For the scalar mode, the sub-elements of the one element operand are processed by the sub-processing units concurrently but independently to generate a scalar result.

摘要： The AGC circuit and method especially applicable in circuits where fast response and stability of the system is necessary, such as where input signals are speech patterns. A gain feedback loop repeatedly adapts the gain and a long term average energy E.sub.mean of the output signal until it approaches a predetermined level. In each pass through the gain feedback loop the long term average energy E.sub.mean is increased by a gain compensation parameter directly proportional to a gain change, thereby rapidly adapting the long term average energy E.sub.mean to converge to the predetermined level.

摘要： The signal processor including a CPU 10 which selects a context register 16, the contents of which configure an address generator 20 and a data type converter 22. A narrow parameter from the CPU 10 produces a broad address for the generator 20 to pass to the memory 28. The converter 22 converts data between memory 28 format and CPU 10 format. A different context register 16 may be selected by each code line of software. The generator 20 preferably calculates a data element length which is the product of an odd number and a power of two, each number being specified in the content of the Context Register 16. Elements are clustered into groups, one group for each element length, and the groups are arranged in order of ascending element length. The index identifying the individual element of a group with a larger element length does not begin with zero (or one). Instead, the lowest index used is sufficiently large that the memory space which would have been occupied with lower indexed elements may instead be occupied by the groups of smaller element lengths.

摘要： An apparatus and method for recording at least two separate incoming signals which reduces computational complexity and memory requirements of the recording device. In one embodiment, the apparatus records and stores the first arriving signal using a high-compression algorithm to reduce memory requirements. Upon receipt of a second signal concurrent with the first arriving signal, the apparatus records and stores the second signal using a second compression algorithm with a lower compression ratio. The second algorithm requires less hardware or processor resources while still providing a moderate degree of compression in relation to the first algorithm. Upon completion of receipt of the first arriving signal, the second signal which was compressed using the second algorithm is decoded and then re-encoded using the first high-compression algorithm. This further reduces memory storage requirements without requiring additional hardware or processor capability. It is contemplated that one embodiment of the subject invention comprise a two line telephone answering machine.
