Arm Architecture: Devices
built 659 days ago
The ARM architecture and the family of devices based on ARM cores are perfect complementary platforms for InterNiche Device Networking products. NicheStack TCP/IP suites have a long track record of design wins on ARM based products and a very successful partnership with the ARM community.

In ARMv7 processors, L2 cache is considered part of the architecture. For earlier versions, it was optional. In Windows Embedded CE, support for L2 cache is limited to enabling L2 cache write-back and discard on L1 cache write-back and discard. Hardware support for L2 cache is dictated by the OEM-specific code. Enabling L2 cache support in the OEM adaptation layer (OAL) resembles other cache operations in the OEMCacheRangeFlush function implementation. Typically, if a device supports L2 cache, OAL code is updated to honor L2 cache flush flags passed to OEMCacheRangeFlush and discard or write back L2 cache accordingly.

Optimized for the latest generation of deployed ARM architecture, the On2-Hantro codecs enable rich multimedia and internet experiences on mobile devices. The codecs drive all genres of mobile video applications from camcorder through to enabling the enjoyment of web-based UGC sites such as YouTube, whilst on the go.

The STM32 delivers impressive levels of performance and energy efficiency, while retaining the benefits of working with the open, industry-standard ARM architecture and development environment. The STM32F103 "Performance" line, with 72MHz clock frequency, provides best-in-class 32-bit MCU performance, while the STM32F101 "Access" line, with 36MHz clock frequency, offers users of 16-bit devices a significant increase in performance, but at 16-bit price levels.

Today, the ARM family accounts for approximately 75% of all embedded 32-bit RISC CPUs,[1] making it one of the most prolific 32-bit architectures in the world. ARM CPUs are found in all corners of consumer electronics, from portable devices (PDAs, mobile phones, media players, handheld gaming units, and calculators) to computer peripherals (hard drives, desktop routers). Important branches in this family include Marvell's XScale and the Texas Instruments OMAP series.
