The ARM9 processor family is built around the ARM9TDMI processor and incorporates the 16-bit Thumb instruction set, which improves code density by as much as 35%. The ARM9 family's comprehensive feature set enables developers to implement leading-edge systems, while delivering considerable savings in chip area, time-to-market, development costs and power consumption. The ARM9 Thumb family includes the ARM920T and ARM922T cached processor macrocells, each of which has been developed to address different application requirements: - - Dual 16k caches for applications running Symbian OS, Palm OS, Linux and Windows CE
- - Dual 8k caches for applications running Symbian OS, Palm OS, Linux and Windows CE
