The majority of contemporary mobile devices and personal computers are based on heterogeneous computing platforms that consist of a number of CPU cores and one or more graphics processing units (GPUs). Despite the high volume of these devices, there are few existing programming frameworks that target full and simultaneous utilization of all CPU and GPU devices of the platform. This article presents...
We present the design exploration and the performance evaluation of a mobile transmitter digital predistortion (DPD) module on a mobile GPU. Digital predistortion is a widely used technique for suppressing the spurious spectrum emission caused by the imperfection of power amplifier and radio frequency (RF) circuits in a real wireless transmitter. Considering the parallel architecture, numerous computing...
The demand for high performance yet extremely low-power multimedia accelerators for mobile communication is ever growing. To meet this challenge a novel approach with a very low-power programmable TTA processor is proposed in this paper. The processor is benchmarked with two OpenCL computer vision applications; depth estimation and face detection. The former is an excellent example of a highly parallel...
