Digital signal processor with selective sound operation |
摘要 |
A digital signal processor (DSP) comprises a condition flag register directly accessible by the control microcomputer. Referring to a condition flag of the condition flag register every sampling period of the DSP, the DSP can change the content of a process every sampling period in accordance with the set status of the condition flag. The DSP sets the condition flag in the condition flag register at the beginning of a sampling period of the DSP by a set instruction, and resets the condition flag at the end of a sampling period by a reset instruction. The DSP may be modified to automatically reset the condition flag at the end of the sampling period in which the condition flag has been set.
