ODC² - On-demand Coherent Cache for Multi-Core CPUs

31.03.2014

An increasing portion of digital devices nowadays is based on multi-core CPUs. Besides consumer gear like smart phones, tablet PCs, game consoles, (smart) TVs etc. multi-core CPU comprising devices are the groundwork in particular for modern automotive, aerospace and industrial control applications. To provide high data access rates each core of a typical CPU is equipped with a fast private (L1) cache. All cores commonly share the comparably slow main memory (and L2 cache). To avoid data inconsistencies due to multiple write accesses the cache controllers implement cache coherence protocols. However, the communication Overhead increases with the number of CPU cores. This leads to an increase of the necessary chip area as well as to an increase of power consumption. Furthermore automotive, aerospace and industrial control applications demand hard real-time abilities. But the known cache coherence arrangements hardly provide this hard real-time functionality. All in all permanently increasing demands concerning processing speed, battery operation time, chip miniaturization level and particularly hard real-time constraints challenge the developers to offer a simple and reliable solution. The novel approach to meet this market demand is the On-demand Coherent Cache (ODC²) recently developed at the Robotics Research Institute of the TU Dortmund University.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

Im Focus: Topological material switched off and on for the first time

Key advance for future topological transistors

Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
