Low Cost Dynamic Architecture Adaptation Schemes For Drowsy Cache Management, Nitin Prakash Jan 2013

Low Cost Dynamic Architecture Adaptation Schemes For Drowsy Cache Management, Nitin Prakash

Masters Theses 1911 - February 2014

Energy consumption and speed of execution have long been recognized as conflicting requirements for processor design. In this work, we have developed a low-cost dynamic architecture adaptation scheme to save leakage power in caches. This design uses voltage scaling to implement drowsy caches. The importance of a dynamic scheme for managing drowsy caches, arises from the fact that not only does cache behavior change from one application to the next, but also during different phases of execution within the same application. We discuss various implementations of our scheme that provide a tradeoff between granularity of control and design complexity. …


Design Of An Open-Source Sata Core For Virtex-4 Fpgas, Cory Gorman Jan 2013

Design Of An Open-Source Sata Core For Virtex-4 Fpgas, Cory Gorman

Masters Theses 1911 - February 2014

Many hard drives manufactured today use the Serial ATA (SATA) protocol to communicate with the host machine, typically a PC. SATA is a much faster and much more robust protocol than its predecessor, ATA (also referred to as Parallel ATA or IDE). Many hardware designs, including those using Field-Programmable Gate Arrays (FPGAs), have a need for a long-term storage solution, and a hard drive would be ideal. One such design is the high-speed Data Acquisition System (DAS) created for the NASA Surface Water and Ocean Topography mission. This system utilizes a Xilinx Virtex-4 FPGA. Although the DAS includes a SATA …
