This framework is based on an operation-centric abstraction for hardware description. In an operation-centric description, the behavior of a system is decomposed and described as a collection of atomic operations. text/html 2021-12-15T22:39:35+00:00 Anonymous (anonymous@undisclosed.example.com) https://users.ece.cmu.edu/~jhoe/doku/doku.php?id=pipeline_synthesis_from_transaction-based_specifications&rev=1639607975&do=diff Pipeline Synthesis From Transaction-based Specifications Pipelining is a classic and widely used microarchitectural optimization to improve performance and efficiency. Pipelining a datapath by hand is tedious and error prone, as it requires the designer to reason about subtle corner cases when sequentially dependent operations are processed concurrently in different pipeline stages. Adding pipeline optimizations such as forwarding, speculation, and multithreading further exacerbates the problem… text/html 2021-11-22T03:35:38+00:00 Anonymous (anonymous@undisclosed.example.com) https://users.ece.cmu.edu/~jhoe/doku/doku.php?id=projects_for_graduate_computer_architecture_courses&rev=1637552138&do=diff (Inactive Page) Projects for Graduate Computer Architecture Courses I developed these four projects with Kai Yu and Eric Chung, for CMU 18-741 Advanced Computer Architecture in Fall 2005. The projects were given out in synch with the lectures. Each project lasts 2 to 3 weeks. The emphasis is on really figuring out what is going on in these bread-and-butter topics. text/html 2021-11-22T03:32:02+00:00 Anonymous (anonymous@undisclosed.example.com) https://users.ece.cmu.edu/~jhoe/doku/doku.php?id=reliable_processors_and_systems&rev=1637551922&do=diff Reliable Processors and Systems This research investigates the impact of soft-error tolerance in future deep-submicron microprocessor designs. The study investigates different options to achieve the desired level of protection against soft errors. This research effort is in part supported by NSF through a CAREER Award.

It employs systematic sampling to measure only a very small portion of the entire application being simulated. The accelerated simulation rate allows complete benchmarks to be used in performance studies.
