ARM-Advanced RISC Machines

ARM (Advanced RISC Machines) can be considered both as a company's name, as a general term for a type of microprocessor, and as a technology name.

ARM Corporation was established in the UK in 1991

Wireless device manufacturers, industry-leading device manufacturers such as Nokia, Sony Ericsson, Palm, Hewlett-Packard, and Sony, and major design manufacturers such as Acer, LuckyGoldstar, HTC, Sendo, and others have announced support for TI's OMAP processor platform . In addition, leading OS vendors, including Symbian, Microsoft, Sun Microsystems and others, have worked closely with TI and have migrated their solutions to TI's OMAP processors. The OMAP platform provides an easy-to-use open programming environment for software application developers by supporting Symbian OS, Microsoft PocketPC 2002, and Windows CE; Palm OS, Linux, Java, ARM Instruction Set, and C / C ++.

TI has also invested a lot of money in developing and expanding its OMAP developer network, a community of international software developers dedicated to creating new applications. By providing multiple tools, training, and a global network of independent OMAP technology centers, TI enables developers and customers to rapidly develop new applications and products.

At present TI's mainstream application processor is OMAP730. OMAP730 is a single-chip processor that integrates the ARM926TEJ application processor and TI's GSM / GPRS digital baseband. Because 40 peripherals are integrated in a single chip, the OMAP730-based design requires only half the board space of the previous generation processor. In addition, OMAP730 has a unique SRAM frame buffer for improving the processing performance of streaming media and applications. The OMAP730 processor also provides sophisticated hardware encryption functions, including encrypted bootloader, operation encryption mode, encrypted RAM and ROM, and hardware acceleration for some encryption standards.

The TCS2600, which uses the OMAP730 processor, is the mainstream smartphone platform launched by TI. It is a new low-power and low-cost option. It takes full advantage of the TI OMAP? Platform to achieve secure mobile commerce and multimedia games And entertainment, location services, streaming, higher-speed Java processing, web browsing, enhanced 2D graphics, support for high-level operating systems, and many other applications. The function of the entire platform is realized on a 53.20mm × 31.25mm printed circuit board, which has a lower cost than other solutions with the same features and memory. Another feature is the extremely low power consumption, which can greatly extend the battery life. This solution can be upgraded to support the requirements of the EDGE protocol. Facing the needs of JAVA, it uses JAVA hardware acceleration and integrates USB, SD / MMC / SDIO, Bluetooth ?, 802.11 high-speed link, Fast IrDA and other peripherals.

In addition, the TCS2600 also provides unparalleled security features. Through the use of a secure boot loader, a true hardware random number generator (RNG), a secure execution and storage environment, and hardware accelerators, a large number of encryption and one-way hashing algorithms can be implemented. Prevents virus attacks and ensures the security of personal information and proprietary software or creative content stored in mobile terminals. In terms of flexibility, TI's smart phone platform can be easily integrated with TI's WLAN and Bluetooth solutions, and will provide users with different and personalized products with enhanced capabilities.

For Chinese OEMs, if they want to gain a leading market position in the future 2.5G / 3G wireless market, choose one that can provide a complete set of solutions including wireless software protocols, digital baseband, power management, application processors, analog baseband, Manufacturers of RF, embedded memory, and reference designs with excellent integration capabilities are critical. As a leading semiconductor supplier of GSM, TI undoubtedly occupies a leading position in the wireless field. In view of the future development trend of the smart phone market, according to IDC, with the development of mobile data value-added services, the global high-end smart phone will grow at a high speed of more than 100% per year, and will climb to 20 million units in about 2006. The development of the domestic smart phone market is even more rapid, with an average annual growth rate of 220%. By providing the industry's highest-performance DSP, the lowest power analog components, and the deepest experience in integrated circuit technology, TI looks forward to playing an irreplaceable role in promoting the future development of the Chinese smartphone market.
