Samsung has announced the development of a new mobile processor based on an ARM core capable of running at 667 MHz. The fastest processor currently in use is 624 MHz, which first appeared in the Dell Axim X30 Advanced 624 MHz. The new ARM 1020E-based chip sports 64 KB of cache, as well as an embedded vector floating point co-processor. It includes six instruction pipelines and runs a 133 MHz system bus.
Many mobile processors are designed to support only integers (whole numbers), not more complicated floating-point (decimal, fractional) numbers in order to save complexity and development costs. Most business applications are all integral-based, but multimedia applications often make heavy use of floating-point math. While it is possible to mimic floating-point numbers on an integer-based processor, it is not easy and the program suffers a major performance hit. A processor with floating point capabilities built in is much more friendly toward decoding compressed audio and video applications.
