    摘要: A variable frequency decoding apparatus operable in a portable audio device that can improve the power management is disclosed. The above apparatus has a decoder and a clock generator that provides the system clock for the decoder. When a bit stream representing audio compressed data is received, the decoder simultaneously provides the audio information embedded in the audio compressed data such as the bit rate and the sampling frequency of the data frame to the clock generator, and then the clock generator adjusts the clock signals; which are used by the decoder to restore to the original PCM format, to match the audio information embedded in the data frame. This audio signal compression technique can prevent possible output delay and reduce power consumption as compared with the conventional way that used a fixed sys clock.

    摘要: A method of improving performance and power utilization of portable a CD player with an electronic anti-shock system (EASS) is disclosed. When PCM signals are received by the EASS, the audio signals are compressed with a high compression rate algorithm and saved in a temporary memory, and later when the audio data are read out from the temporary memory, the audio data are decoded with the same audio compression algorithm to restore to the original PCM format, thus a data buffering is created between the reading of data and the playback of sound. A high compression rate algorithm can increase the utilization of DRAM memory and lengthen the buffering time considerably. The present invention has incorporated an audio compression algorithm having high compression rate in the EASS to attain the most desirable balance point between audio performance, power management, and costs.

    摘要: A method of optimizing the compression rate in Adaptive Differential Pulse Code Modulation (ADPCM) is disclosed. The modified pulse code modulation technique employs a prognostic code converter to generate variable length codes on top of the ADPCM coding, based on the probability of occurrence of data bits in a data sample. This variable-length coding is able to further reduce the compressed data size by increasing the compression rate of the conventional ADPCM coding.

    摘要: A program redirection and modification method for embedded processors with a limited amount of SRAM sets at least one address in a program of ROM to an origin address of at least one register. To redirect the embedded processor to execute another section in the program in ROM or SRAM, a destination address of the register is set to another address of the program in ROM or a program in the SRAM. Therefore, the embedded processor sets the addresses in the register and then the program in ROM can debugged or extended to an external program.

    摘要: A thermal control system for variable speed microprocessor with a piecewise estimate of temperature change. The estimate is modeled after actual temperature change measurements of a microprocessor operating at low and high speeds and is recorded in a digital format in storage registers, one set of registers for each operating frequency. A counter counts sample microprocessor clock signals for a time over which the microprocessor speed is operating at a specific speed and provides a basic count signal. This basic count signal is incremented or decremented by comparison with stored values of the piecewise estimate of temperature change. As the basic signal increases or decreases, new slopes are provided to the counter for adjusting the basic count, upwards or downwards, depending on whether the system speed is high, intermediate or low. The adjusted counter output is also fed to comparators, which monitor a desired upper and lower temperature limit. As the upper limit is approached, control logic implements a throttling algorithm to maintain temperature in the desired range. The present invention takes into account the operating history of the system in a particular environment since the system powers on, including idleness of the system.
