Utilizing RF-I and intelligent scheduling for better throughput/watt in a mobile GPU memory system

Abstract

Smartphones and tablets are becoming more and more powerful, replacing desktops and laptops as the users' main computing system. As these systems support higher and higher resolutions with more complex 3D graphics, a high throughput and low power memory system is essential for the mobile GPU. In this article, we propose to improve throughput/watt in a mobile GPU memory system by using intelligent scheduling to reduce power, and multi-band radio frequency interconnect (MRF-I) to offset any throughput degradation caused by our intelligent scheduling. Overall, we are able to improve throughput 17% up to 66% while increasing throughput per watt by an average of 18% up to 26%.

“…Consequently the memory bandwidth is also much lower when compared to desktops GPUs [11]. Currently, mobile GPUs emphasis more on lower power consumption [12] than performance. Some of these currently available GPUs devices are the Qualcomm's Adreno 200, the TI's PowerVR SGX 530/535 and the nVidia Tegra3.…”
