Data processing system and method for music synthesizing system

Abstract

Based on music processing requirement, the system processes first preset amount of music data in order to obtain second preset amount of music data. The system includes first memory, a music data processing unit, and second memory. The first memory stores multiple parts of music data. The music data processing unit possesses functions: (1) receiving requirement of music processing; (2) based on requirement of music processing, fetching out first preset amount of music data stored in first memory; (3) based on a data processing formula, calculating out a data processing value from adjacent two parts of music data in the first preset amount of music data so as to obtain second preset amount of music data. Second memory is for storing the processed value of second preset amount of music data. The invention reduces requirement for processor in known handheld device, and reduces cost effectively.

Description

technical field [0001] The present invention relates to a data processing system applied in a music synthesis system, which is used for sequentially processing a first predetermined number of pieces of music data in a handheld device (such as a mobile phone handset) to accumulate and synthesize a digital music signal. Background technique [0002] Known mobile phone handsets have two main functions: 1. Listening, speaking and data transmission—executed using systems such as GSM, GPRS and CDMA; 2. Multimedia applications—such as games, digital music (MIDI), music and digital cameras Wait. Since the development of mobile phones, various new functions have been derived. Taking GSM and GPRS as examples, one of the applications that has attracted much attention is multimedia short message. Multimedia Message Service (Multimedia Message Service, MMS), as its name implies, is a short message that can transmit multimedia content, including a variety of color pictures, animated car...

AI Technical Summary

Problems solved by technology

This method will cause some disadvantages: 1. Waste of hardware resources and costs, 2. Cannot improve processing efficiency, 3. Make the system more complicated

Because the DSP of this invention processes music data directly through the peripheral component connection interface (PCI), there is no specific hardware to accelerate, which will consume a large amount of computing power of the DSP

If this technology is used in a mobile phone with a small size and limited computing power, a simple DSP will not be able to handle huge music data calculations
