Time synchronization method and system for multi-core system

The invention discloses a multi-core system time synchronization method and a system thereof; the time synchronization method comprises the following steps: A, establishing at least a clock synchronization domain, and distributing the cores respectively into each lock synchronization domain; B, selecting the core with the minimum load as the master clock synchronization source in each clock synchronous domain, and taking the clock synchronization domain having the master clock synchronization source with the minimum load among all the master clock synchronization sources as the master clock synchronization domain, and taking the other clock synchronization domains as the slave clock synchronization domains; C, after the master clock synchronization domain sends synchronization error detection information to each slave clock synchronization domain, calculating the time deviation value between each slave clock synchronization domain and the master clock synchronization domain; D, when the time deviation value is greater than the permitted deviation value, the master clock synchronization domain calculates the time adjustment quantity of each slave clock synchronization domain and releases the time adjustment quantity to each slave clock synchronization domain, then each slave clock synchronization domain makes adjustment based on the corresponding time adjustment quantity. The invention effectively solves the time synchronization problem of the multi-core system.

Automated performance technology using audio waveform data

In order to play waveform data back at a variable performance tempo by using waveform data which complies with a desired reference tempo, the present invention performs a timeline-expansion/contraction control on the waveform data to be played back, according to the relationship between the performance tempo and the reference tempo. The present invention also determines whether to limit the playback of the waveform data according to the relationship between the performance tempo and the reference tempo. In the case that playback is to be limited, the present invention stops playback of the waveform data, or reduces the resolution of playback processing and continues playback of the waveform data. The present invention stops playback of the waveform data when, for example, the relationship between the performance tempo and the reference tempo is a relationship in which the waveform data would be played back at a performance tempo which would cause a processing delay or a deterioration of sound quality. As a result, it is possible to preemptively prevent a system freeze and solve problems such as the generation of music which has a slower tempo than the desired performance tempo, or the generation of music which includes the intermittent cutting out of sound due to noise, or a significant reduction to sound quality.
