Implementing Fast Barriers For A Shared-Memory Cluster Of 1024 RISC-V Cores


A technical paper titled “Fast Shared-Memory Barrier Synchronization for a 1024-Cores RISC-V Many-Core Cluster” was published by researchers at ETH Zürich and Università di Bologna. "Synchronization is likely the most critical performance killer in shared-memory parallel programs. With the rise of multi-core and many-core processors, the relative impact on performance and energy overhe... » read more

Big Shift In Multi-Core Design


Hardware and software engineers have a long history of working independently of each other, but that insular behavior is changing in emerging areas such as AI, machine learning and automotive as the emphasis shifts to the system level. As these new markets consume more semiconductor content, they are having a big impact on the overall design process. The starting point in many of these desig... » read more

Power/Performance Bits: June 21


A chip with 1,000 processors A microchip containing 1,000 independent programmable processors has been designed by a team at the University of California, Davis. Called the KiloCore chip, it contains 621 million transistors and was fabricated by IBM using its 32nm CMOS technology. Cores operate at an average maximum clock frequency of 1.78 GHz, and they transfer data directly to each other r... » read more

Multicore: Is More Better?


By Frank Ferro Two cores are better than one, right? It reminds me of those AT&T commercials where they ask the kids, “Who thinks two is better than one?” And of course the kids all yell, two! In another version of the commercial they ask; “What’s better, doing two things at once or just one?” And again they all yell, two! Well, this is a good summary or of last week’s Multicor... » read more

Low Power Drives New Architectures


By Pallab Chatterjee Power became the driving discussion at several major events last month. The global cries for energy reduction, which have been mainstream since the early 1970s on the political level, have now moved to being real economic realities for component and systems suppliers. Chipmakers are finding that lower power makes good economic sense—lower cost of packaging, lower cost... » read more
