ARM926EJ™ 32-bit processor
The ARM9EJ™ industry standard ARM® processor enables single processor solutions for microcontroller, DSP and Java applications, offering savings in chip area and complexity, power consumption, and time-to-market. The ARM9EJ is a DSP-enhanced 32-bit RISC processor, well suited for applications requiring a mix of DSP and microcontroller performance. The processor has been developed to address different application requirements, and implement the 16-bit Thumb® instruction set giving excellent code density, maximising savings on system cost. The ARM926EJ processor also includes ARM Jazelle™ technology which enables the direct execution of Java bytecodes in hardware.
