Please consult the board-support guide or contact us for specific platform features supported. The Intel® PXA255 XScale® processor is a highly integrated, 32-bit RISC processor that combines the efficiency of Intel design with the ARM® v.5TE instruction-set architecture. The BSQUARE XScale PXA255 DevkitIDP™ reference platform from helps speed the development cycle of products that incorporate the Intel PXA255 XScale processor—such as personal assistants (PDA), wireless web pads, set-top boxes, Internet audio and video devices, kiosks and point-of-sale (POS) products. The PXA255 is based on Intel XScale technology and boasts a new, fast 200Mhz internal system bus. The PXA255 is a pin-for-pin compatible, drop-in replacement for the Intel PXA250 XScale processor. The Intel PXA255 processor delivers industry-leading processing power with built-in multimedia capabilities for high performance and hand-held functionality. High-performance, low-power Intel XScale technology core at 200, 300 and 400 MHz (new power management for low power) Faster internal system bus aAt 400 MHz core, internal bus runs at 200 MHz vs. 100 MHz on the Intel PXA250 processor) Intel media processing technology Enhanced memory controller MMC/SD and PCMCIA/CF card support 1.84 MHz cellular baseband interface 920 Kbps Bluetooth interface Variable latency I/O The Intel PXA255 processor cost-effectively boosts processing speed and power management over the Intel PXA250 processor. Power management features enable lower power dissipation; up to 60 percent less than previous Intel XScale technology-based products. And the processing capabilities of the Intel PXA255 processor enable portable devices to respond fast to optimized operating systems and performance intensive applications like MPEG4 video, speech and handwriting recognition, and Java interpretation. Intel's robust software and hardware development environment offers a large library of ARM-compliant applications and tools, as well as an array of wireless operating systems and tool chains to ease application development and system prototyping. The Intel Integrated Performance Primitives (Intel IPP) library promises easy access to an array of low-level, cross-platform software algorithms for high-demand communications, signal processing, mathematics and media functions. The Intel IPP's highly optimized implementation helps reduce battery consumption through more efficient CPU execution. View more Intel boards, or learn more about Intel—a SynergyWorks partner.
