Run-time mixed-grained reconfigurable architectures emerged as an efficient solution to deal with the heterogeneous and at-design-time unpredictable nature of advanced applications. Due to interconnection limitations, the reconfigurable elements are grouped into tiles communicating through an on-chip network. State-of-the-art run-time accelerator binding schemes, i.e., mapping the accelerators to...
The High Efficiency Video Coding (HEVC) standard aims at providing ∼50% better compression compared to its predecessor (H.264) at the cost of high computational complexity. To enable HEVC video encoding in real-time scenarios, special coding support for parallelization is provided in HEVC that can be exploited by many-core systems. In this work, we present a HEVC software architecture where a video...
An energy-efficient distributed Scratchpad Video Memory Architecture (dSVM) for the next-generation parallel High Efficiency Video Coding is presented. Our dSVM combines private and overlapping (shared) Scratchpad Memories (SPMs) to support data reuse within and across different cores concurrently executing multiple parallel HEVC threads. We developed a statistical method to size and design the organization...
This paper provides a comprehensive analysis of the computational complexity, power consumption, temperature, and memory access behavior for the next-generation High Efficiency Video Coding (HEVC) standard. We highlight the associated design challenges and present several low-power algorithmic and architectural techniques for developing power-efficient HEVC-based multimedia system. We explore the...
Facing the requirements of next generation applications, current approaches of embedded systems design will soon hit the limit where they may no longer perform efficiently. The unpredictable nature and diverse processing behavior of future applications requires to transgress the barrier of tailor-made, application-/domain-specific embedded system designs. As a consequence, next generation architectures...
