ARM926EJ-S , ARM946E-S, ARM966E-S, ARM968E-S and ARM996HS The ARM9E processor family enable single processor solutions for microcontroller, DSP and Java applications, offering savings in chip area and complexity, power consumption, and time-to-market. The ARM9E family of products are DSP-enhanced 32-bit RISC processors, well suited for applications requiring a mix of DSP and microcontroller performance. The family includes the ARM926EJ-S, ARM946E-S, ARM966E-S, ARM968E-S and ARM996HS processor macrocells, each of which has been developed to address different application requirements. They include signal processing extensions to enhance 16-bit fixed point performance using a single-cycle 32 x 16 multiply-accumulate (MAC) unit, and implement the 16-bit Thumb® instruction set giving excellent code density, maximising savings on system cost. The ARM926EJ-S processor also includes ARM Jazelle™ technology which enables the direct execution of Java bytecodes in hardware.
- Jazelle technology, memory management unit (MMU), variable size instruction and data caches (4K - 128K), instruction and data tightly coupled memory (TCM) interfaces
- Variable size instruction and data cache (0K- 1M), instruction and data TCM(0 - 1M), and memory protection unit for embedded applications.
- Targets "hard real-time" applications requiring predictable instruction execution timings with high performance and low power consumption.
- The smallest, lowest power ARM9E family processor to date, aimed specifically at embedded real-time applications.
- MOVE Video Coprocessor. This coprocessor for ARM9E family processors accelerates the Sum of Absolute Differences (SAD) operation used in MPEG-4 Encoder Motion Estimation.
