The ARM9 family processor is ARM's UK mainstream embedded processor design, including ARM9TDMI and ARM9E-S series. Mobile phone applications, for example, 2G phones only provide voice and simple text messaging, and the current 2.5G and future 3G mobile phones in addition to providing these two functions, must also provide a variety of other applications. Include: (1) wireless network devices: mobile Internet, e-mail and other location based services and other functions; (2) PDA function: with the user operating system (Windows CE, Symbian OS, Linux, etc.) and other functions; (3) high performance features: audio player, video phone, mobile phone games. 2.5G and 3G applications ARM9 has been fully replaced ARM7. Because new features to meet the ARM9 new needs while reducing product development time and reduce development costs.
