Processors in Windows Mobile devices have been pretty stable for some years (with the dreaded Qualcomm chips that is), but now innovation appears to be ramping up pretty rapidly, and we should see the fruits of that in our devices pretty soon.
Samsung and Intrinsity have announced what they believe to be the fastest mobile processor core implementation of the dual issue ARM Cortex-A8 processor architecture.
The 45nm chip, code named Hummingbird, comes with 32kbyte data and instruction caches, as well as a customisable L2 memory cache, runs at 1Ghz and delivers 2000DMIPS.The core also features an ARM NEON multimedia extension.
Low power consumption and high operating clock performance make Hummingbird ideal for use in
smartphones.
“The biggest challenge in mobile processor core design and implementation is to achieve high clock speed performance while keeping the power consumption low," said Dr Jae Cheol Son, vp of SoC platform development within Samsung’s system lsi division. "The collaboration between Samsung and Intrinsity combines the best design and implementation technologies in the industry in successfully meeting the aggressive performance and power consumption targets of the Hummingbird.
Intrinsity ceo Bob Russo added: "Mobile device end users want smoother video, faster gaming and a longer battery life. Meeting these conflicting demands typically means building a new processor implementation from scratch."
