Parallel JPEG Color Conversion on Multi-Core Processor

Multigrain Parallel Processing for JPEG Encoding on a Single Chip Multiprocessor

GPU-Parallel Implementation of Color based Medical Image Retrieval in Compressed Domain

In huge databases Image processing takes more time for execution on a single core processor because of slow single thread algorithms. Graphics Processing Unit (GPU) is more popular now-a-days due to their speed, programmability, low cost and more inbuilt execution cores in it. Most of the researchers started work to use GPUs as a processing unit with a single core computer system to speedup exe...

Multi-Core Simulation of Transaction Level Models using the System-on-Chip Environment

Effective Electronic System-Level (ESL) design frameworks transform and refine high-level designs into various transaction level models described in C-based System-level Description Languages (SLDLs) and rely on simulation for validation. However, the traditional cooperative Discrete Event (DE) simulation of SLDLs is not effective and cannot utilize any existing parallelism in todays’ multi-cor...

Parallel Streaming Computation on Error-Prone Processors

Hardware fault rates are increasing due to decreasing transistor sizes in newer technology nodes. To ensure reliability, circuits need more redundancy and higher voltage margins, incurring high area/performance/energy overheads. Since some applications, such as multimedia processing and streaming applications, can tolerate some types of errors, approximate computing research has begun exploring...

Ultra-Low-Energy DSP Processor Design for Many-Core Parallel Applications

Background and Objectives: Digital signal processors are widely used in energy constrained applications in which battery lifetime is a critical concern. Accordingly, designing ultra-low-energy processors is a major concern. In this work and in the first step, we propose a sub-threshold DSP processor. Methods: As our baseline architecture, we use a modified version of an existing ultra-low-power...
