Abstract-In this paper, design and implementation of an asynchronous high speed data acquisition and transfer system based on DSK6416 evaluation board is presented. This board has Texas Instruments' TMS320C6416T Digital Signal Processor (DSP) chip which belongs to TMS320C64X family. Despite DSK6416 evaluation board acquires data at 96kHz sampling rate with its integrated audio codec chip, TLV320AIC23, we increased data acquisition speed to 5.68MHz using with THS1206EVM Analog Digital Converter (ADC) board. As a result, data acquisition capability of DSK6416 board enhanced from hearable sound range to ultrasonic sound range (>20kHz). DSK6416 board can be used as a digitizer unit in the NonDestructive Testing (NDT) systems after this hardware revision. Data transfer speed between DSP chip and ADC board is 62.5MHz this provides short data acquisition time (16ns) for each read operation from ADC. Thus plenty of time remains for digital signal process tasks. Keywords -DSP, TMS320C64X, DSK6416, High Frequency, ADC, NDT, Ultrasonic. 978-1-4799-4874-1I14/$3l.00 ©2015 IEEE I.

-The performance of data interaction between different memories has become a significant factor in the complex embedded systems with the huge increase of processing needs, especially between internal chip-on memory and external memory. This paper advances a constructive optimized scheme named global direct memory access (GDMA) for high-speed data interaction in the multi-core digital signal processor (DSP) systems. Furmore, we give important recommendations to actualize software programming optimization of GDMA from three aspects.This scheme is based on the key technique of enhanced direct memory access versions3 (EDMA3), quick direct memory access (QDMA) and internal direct memory access (IDMA). This scheme can enhance the peak speed of data interaction between local memories by 53.8% and 2.5% averagely for some situations using QDMA compared EDMA3. By establishing the bridge memory area, the speed from level-1 data memory to external memory is optimized by 15.3% maximumly. The multi-core DSP system can achieve the performance of high-speed data interaction at around 5GBps to meet user expectations.
