ARM920T and ARM922T
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 family consists of the ARM922T cached processor macrocell.
