Technology scaling and growing use of accelerators make optimization of data movement of increasing importance in all computing systems. Further, growing diversity in memory structures makes embedding such optimization in software non-portable. We propose a novel architectural solution called Data Layout Transformation (DLT) associated with a simple set of instructions that enable software to describe...
In this paper, we perform a systematic comparison to study the energy cost of varying data formats and data types w.r.t. arithmetic logic and data movement for accelerator-based heterogeneous systems in which both compute-intensive (FFT accelerator) and data-intensive accelerators (DLT accelerator) are added. We explore evaluation for a wide range of design processes (e.g. 32nm bulk-CMOS and projected...
Accelerators have long been used to improve the performance and energy efficiency of embedded signal processing systems relying on Fast Fourier Transforms (FFTs). We explore the benefits of processor-integrated FFT accelerators, characterizing their performance and energy efficiency for current and future memory architectures. First, we consider designs that deeply integrate an FFT accelerator into...
