An energy-efficient hybrid on-chip video memory architecture (enHyV) is presented that combines private and shared memories using a hybrid design (i.e., SRAM and emerging STT-RAM). The key is to leverage the application-specific properties to efficiently design and manage the enHyV. To increase STT-RAM lifetime, we propose a data management technique that alleviates the bit-toggling write occurrences...
Pipelined MPSoCs provide a high throughput implementation platform for multimedia applications. They are typically balanced at design-time considering worst-case scenarios so that a given throughput can be fulfilled at all times. Such worst-case pipelined MPSoCs lack runtime adaptability and result in inefficient resource utilization and high power/energy consumption under a dynamic workload. In this...
In this work, we present a novel frame-level Rate Control algorithm for Multiview Video Coding encoder that adopts the Model Predictive Control technique in order to provide low bitrate fluctuation and high video quality. Our Model Predictive Rate Control (MPRC) predicts the bitrate for a frame by employing (i) inter-view inter-GOP (Group of Pictures) phase-based bitrate prediction, and (ii) temporal...
Pipelined MPSoCs provide a high throughput implementation platform for multimedia applications, with reduced design time and improved flexibility. Typically a pipelined MPSoC is balanced at design-time using worst-case parameters. Where there is a widely varying workload, such designs consume exorbitant amount of power. In this paper, we propose a novel adaptive pipelined MPSoC architecture that adapts...
