Comparison between ARM9E and ARM10E
The E in ARM10E means the same as in ARM9E, Enhance instrctions, which means enhanced DSP instructions, which shows that ARM9E is actually ARM9 is just an extension and variant.
The ARM10E series microprocessors are comprehensive processors that use a single processor core to provide solutions for microcontrollers, DSPs, and Java application systems, greatly reducing the chip area and system requirements. level of complexity. The ARM9E series microprocessors provide enhanced DSP processing capabilities and are very suitable for applications that require the use of DSP and microcontrollers at the same time.
The difference between ARM10E and ARM9E is that ARM10E uses Harvard structure, 6-stage pipeline, and the main frequency can reach up to 325MHZ, 1.35MIPS/HZ

The main features of the ARM9E series microprocessors are as follows:
1. Supports DSP instruction set, suitable for occasions requiring high-speed digital signal processing.
2. 5-level integer pipeline, higher instruction execution efficiency.
3. Supports 32-bit ARM instruction set and 16-bit Thumb instruction set.
4. Supports 32-bit high-speed AMBA bus interface.
5. Support VFP9 floating point processing coprocessor.
6. Full-performance MMU supports multiple mainstream embedded operating systems such as Windows CE, Linux, and Palm OS.
7. MPU supports real-time operating system.
8. Supports data Cache and instruction Cache, with higher instruction and data processing capabilities.
9. The main frequency can reach up to 300MIPS.
