Approximate adders are widely being advocated for developing hardware accelerators to perform complex arithmetic operations. Most of the state-of-the-art accuracy configurable approximate adders utilize some integrated Error Detection and Correction (EDC) circuitry. Consequently, the accumulated area overhead due to the EDC (integrated within individual adders) is significant. In this paper, we propose...
This paper presents a cross-layer approach for analyzing and designing energy-efficient advanced multimedia systems with next-generation High-Efficiency Video Coding (HEVC) standard. Our approach leverages both algorithmic and architectural layers of system design abstractions in order to achieve a high power/energy efficiency. We present an analysis and design of an HEVC-based multimedia system while...
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...
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...
