PPT-Caches for Accelerators

ECE 751 Brian Coutinho David Schlais Gokul Ravi amp Keshav Mathur Summary Fact Accelerators gaining popularity to improve performance and energy efficiency Problem Accelerators with scratchpads require DMA calls to satisfy memory requests among other overheads. Although large caches can significantly improve performance they have the potential to increase power consumption As feature sizes shrink the dominant component of this power loss will be leakage However during a fixed period of time the activ ity i The accelerators offload the core processor and have the potential to more than double the computational throughput of the processor This paper introduces the accelerators using their application in nextgeneration audio systems as an example Why Har caches and data caches are always identical in size or differ by a factor of 2X, but no more. The primary caches range from 8 KB to 128 KB with SA ranging from direct mapped to 8-way. Small instruct ECE . 751. Brian Coutinho. ,. David Schlais. ,. Gokul Ravi. &. Keshav . Mathur . Summary.

Mandate. Major initiatives are well underway for ion accelerators for nuclear astrophysics, such as FRIB, RAON and others.  With the success of SNS, high intensity proton accelerator projects are progressing, such as ESS, PIP-II, Indian SNS, along with ADS ambitions, such as CADS and IADS.  The aim of WG2 is to address the major on-going issues for each type of accelerator, how these issues are being addressed, as well as the needed developments. Demonstrated and needed advances in couplers and tuners for both accelerator classes should be included.  Please avoid presentations that give project status summaries - more suited to other conferences. . 2.
