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.">
