ARM926EJ-S
The processor is the powerful ARM926EJ-S, targeted for multi-tasking applications.
Belonging to ARM9 general purposes family microprocessor, it principally stands out for the
Memory Management Unit, which provides virtually memory features, making it also
compliant with WindowsCE, Linux and SymbianOS operating systems.
The ARM926EJ-S supports the 32 bit ARM and 16 bit Thumb instruction sets, enabling the
user to trade off between high performance and high code density and includes features for
efficient execution of Java byte codes.
Besides, it has the ARM debug architecture and includes logic to assist in software debug.
