More efficient data cache block prefetch lowers system power and boosts system performance by speeding functions such as MemCpy by 6.
Utilising both sets of criteria, the researchers were able to boost multi-core chip performance by 40 per cent, compared to multi-core chips that do not prefetch data, and by 10 per cent over multi-core chips that always prefetch data.
A sample of the topics includes combining prefetch with instruction cache locking in multitasking real-time systems, optimal scheduling of urgent preemptive tasks, and Wi-Fi fingerprint-based topological map building for indoor user tracking.
A larger prefetch means more data is immediately available for the processor and the differential data strobe reduces noise while accessing data, especially at higher frequencies.
Make search engines auto-complete your search terms, prefetch your results, and remember where you've been-without invading your privacy
Powered by an Intel 866MHz ultra-low-voltage Mobile Pentium III CPU with enhanced SpeedStep technology, the CF-T1 features 256MB of 133MHz SDRAM (expandable to 512MB), 512K on-die L2 cache, a 133MHz system bus, and Data Prefetch Logic for faster data response time.
Also, support from the programming languages for application programmers to effectively use the hardware prefetch instruction is limited or non-existent .
The system is network data-management protocol compatible, and incorporates data prefetch and fast cataloging for maximum device speed.
