Abstract
A method for dynamically arranging DSP tasks. The method comprises receiving an audio bit stream, checking a remaining execution time as the DSP transforms the audio information into spectral information, simplifying the step of transforming the audio information when the DSP detects that the remaining execution time is shorter then a predetermined interval, and skipping one section of the audio information and decoding the remaining section when the execution time is less than a predetermined interval.
Claims19
A method for dynamically arranging DSP a plurality of tasks, wherein each task is associated with an interrupt and a priority, comprising:
- receiving first audio information;
- executing a audio decoding task unless an interrupt having a priority higher than the priority of the audio decoding task interrupts the DSP;
- determining a remaining execution time when the DSP transforming the first audio information into second audio information;
- segmenting the second audio information into two sections according to the remaining execution time when the remaining execution time is shorter then a predetermined interval, wherein the two sections are a remaining section and ignoring section;
- analyzing the remaining section into spectral domain;
- and
- synthesizing the analyzed section.
A method of decoding audio information, comprising:
- receiving the audio information;
- checking a remaining execution time;
- segmenting the audio information into two sections according to the remaining execution time;
- and
- ignoring one section of the audio information and decoding the remaining section when the remaining execution time is less than a predetermined interval.
