Project of DMT modulator in Multicore DSP with FFT Coprocessor

چکیده
This work discusses the characteristics of a multicore processor to perform DMT/OFDM modulation, while eventually executing other concurrent tasks. The DMT modulation is of special interest because it has been adopted in several communication systems. As a case study, the TMS320C6670 is adopted, which has a (I)FFT coprocessor. The use of these coprocessors can be essential to make a DMT/OFDM feasible given that the majority of the computation cost for transmission/reception corresponds to the (I)DFT algorithm. The obtained results indicate that DSP chips with (I)FFT coprocessor are competitive with alternatives such as FPGA, with respect to cost and performance. General Terms DMT / OFDM Modulation, DSP Multicore

متن کاملVersatile design of shared vector coprocessors for multicores
For most of the applications that make use of a vector coprocessor, its resources are not highly utilized due to the lack of sustained data parallelism, which often occurs due to insufficient vector parallelism or vector-length variations in dynamic environments. The motivation of our work stems from (a) the omnipresence of vector operations in high-performance scientific and emerging embedded ...
