Description

Technical field

[0001] The invention relates to a signal processing and analysis technology, in particular to a digital processing method of a handheld instrument. Background technique

[0002] At present, the processing of digital signals mostly uses floating-point operations, but general floating-point operations may be very slow and have errors. With the huge amount of digital signal processing today, it cannot meet the high-demand digital signal processing. And analysis, resulting in DSP not being able to play its maximum role. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings in the prior art and provide a digital processing method for handheld instruments. The present invention combines the dual-core TI dual-core on the basis of the high-precision floating-point computing capability of the OMAP-L138 dual-core processor The data interaction software DSPLINK realizes the data interaction between ARM and DSP,...
