Abstract: A digital voice data storage and retrieval system using a low bit rate encoder which provides enhanced speech signal quality while also reducing memory size requirements. The system comprises a voice coder/decoder which preferably includes a digital signal processor (DSP) and also preferably includes a local memory. During encoding of the voice data, the voice coder/decoder receives voice input waveforms and generates a parametric representation of the voice data. A storage memory is coupled to the voice coder/decoder for storing the parametric data. During decoding of the voice data, the voice coder/decoder receives the parametric data from the storage memory and reproduces the voice waveforms. According to the invention, an interframe smoothing method is performed on the parametric data after encoding of all of the speech data has completed and the parametric data has been stored in the storage memory.

Abstract: A method of managing a memory array having a plurality of erasable sectors. The method initially assigns at least one of the erasable sectors as a storage array and at least one of the erasable sectors as an update array. At least one data file is then sequentially written into the storage array beginning at a starting byte within the storage array. Each data file written into the storage array is initially designated as an active file. Thereafter, one or more of the active files is deleted by re-designating an active file as a deleted file. The deletion of active files is accomplished without erasing any of the erasable sectors. In a presently preferred embodiment, the deletion of files is accomplished by setting an Active/Delete flag in a header of the file. After deleting one or more active files, the array comprises at least one active file and at least one deleted file.

Abstract: A CPU or microprocessor which includes a general purpose CPU component, such as an X86 core, and also includes a DSP core. The CPU also includes an intelligent DSP function decoder or preprocessor which examines X86 opcode sequences and determines if a DSP function is being executed. If the DSP function decoder determines that a DSP function is being executed, the DSP function decoder converts or maps the opcodes to a DSP macro instruction that is provided to the DSP core. The DSP core executes one or more DSP instructions to implement the desired DSP function in response to the macro instruction. The DSP core implements or performs the DSP function using a lesser number of instructions and also in reduced number of clock cycles, thus increasing system performance. If the X86 opcodes in the instruction cache or instruction memory do not indicate or are not intended to perform a DSP-type function, the opcodes are provided to the X86 core as which occurs in current prior art computer systems.

The CPU also includes an intelligent DSP function decoder or preprocessor which examines X8 opcode sequences and determines if a DSP function is being executed. The function preprocessor includes a look-up table which stores instruction sequences which implement DSP functions. Each pattern in the look-up table is compared with an instruction sequence to determine if one of the patterns substantially matches the instruction sequence. If the DSP function preprocessor determines that a DSP function is being executed, the DSP function preprocessor converts the opcodes to a DSP macro instruction that is provided to the DSP.

Abstract: An improved vocoder system and method for estimating pitch in a speech waveform which more accurately disregards false pitch estimates resulting from secondary excitations. The vocoder system first performs a correlation calculation on a speech frame and generates an estimated pitch value. The present invention then compares the estimated or determined pitch with a threshold value to determine if the determined or estimated pitch has a suspiciously low pitch value. If so, the present invention performs error checking to disregard pitch estimates that are the result of the First Formant frequency's contribution to the pitch estimation process. The error checking involves examining the higher multiples of the determined pitch value to ascertain whether the determined pitch value might be incorrect. The present invention determines whether one or more higher multiples are missing, whether the higher multiples are related by a common factor, and whether adjacent multiples have missing peaks.
