Windows CE .NET supports four microprocessor families and simulation technology. § ARM: Supported processors include ARM720T, ARM920T, ARM1020T, STRONGARM, XSCALE § MIPS: Supported processors include MIPS II / 32 with FP, MIPS II / 32 WITHOUT FP, MIPS16, MIPS IV / 64 with FP, MIPS IV / 64 WITHOUT FP § SHX: Supported processors include SH-3, SH-3 DSP, SH-4 § x86: Supported processors include 486, 586, Geode, Pentium I / II / III / IV
From the perspective of Pocket PC, the current model of the current model uses the Intel PXA processor of 0.18 micron process, this series of built-in Xscale technology's Intel PXA family processor, currently launched the latest Intel PXA270.
Intel Xscale Architecture PXA Series Processors are an embedded 32-bit processor after Intel Strongarm. In addition to being applied to handheld, it is also available in smartphones, network storage devices, backbone. Router and other electronic devices. Intel Xscale architecture PXA series processor is compared with "predecessor" Intel Strongarm series processor: 1. The capacity of data Cache is increased from 8KB to 32KB; 2, the capacity of the instruction Cache is increased from 16kb to 32kb; 3, The capacity of minute data Cache increases from 512b to 2 kb; 4, in order to improve the execution speed of the instruction, the super-pipeline structure is increased from 5 to Level 7; 5, new multiplication / adder MAC and a specific DSP-type association processor CP0, To improve support for multimedia technology; 6, dynamic power management allows the xscale processor's clock up to 1GHz, power consumption 1.6W, and can reach 1200MIPS. 7, the main frequency is high, more power saving. Its core uses Intel's advanced 0.18μm process technology manufacturing; with low power consumption, applicable range from 0.1mW to 1.6W. At the same time, its clock operating frequency will approach 1 GHz. Specifically, in the processor of the STRONGARM series, the operating frequency of 133MHz can be obtained at 1.55V, and the operating frequency of 206 MHz can be obtained at 2.0V; and the XScale series processor is at 0.75V to 150MHz, at 1.0V When the operating frequency can reach 400 MHz, the operating frequency at 1.65V can be as high as 800MHz. 8, support multimedia processing technology, using 40-bit accumulators and 16-bit multipliers to enhance decoding capabilities for audio and video. 9, the supported interface is richer. Provide support for USB, CF card, PC card, 802.11b wireless network card, Bluetooth, and infrared rays, supported interfaces. 10. The power management scheme is more perfect. Its power management provides four working modes: Turbo mode, running mode, idle mode, and sleep mode. In Turbo mode, the CPU core is running on the peak frequency, in order to avoid the waiting time of the external memory, in this mode, rarely access the external memory; mode of operation, the CPU core is running at the normal standard frequency, which can assume the kernel Constantly accessing external memory, slowing the speed of operation is advantageous for the optimal balance of performance and power consumption; in idle mode, suspend to the CPU clock, but enable the clock to the peripheral device; sleep mode The entire system will be in the lowest power state, and the system must restart the system.
The PXA27X processor is the currently newly introduced embedded processor currently in Intel. Its clock frequencies from 312 to 624 MHz and built-in 64 MB (Megabytes) stack Intel Strataflash memory. Built-in Intel's wireless MMX technology, can provide higher performance for 3D games and video applications, significantly enhance multimedia performance, the official statement is the 312MHz CPU (the lowest in PXA27X series) will reach the multimedia processing of 520MHz ARM CPU Effectiveness, and the clock frequency reaches 624MHz, you can have a 775MHz ARM CPU performance! In addition, the PXA27x also includes Intel's SpeedStep technology, which can be dynamically adjusted by the CPU performance, which is mobile voltage and operational frequency, which is similar to the Intel notebook computer processor, which has greatly saved the power consumption of the action device. The PXA27x's electricity is even lower than the PXA262. Specifically, the time of playing MP3 can be extended by 42%, and the video time of playback QVGA can be extended by 77%! Intel is released while publishing this series of processors, also released graphics used in conjunction with PXA27X Cooperation processor D D2700G
Multimedia accelerator. It is designed to assist the Intel PXA27x series processor, providing a variety of advanced movies and drawing capabilities, play movies with full screen mode at the highest playback speed, and does not reduce battery usage. Intel
2700g
The multimedia accelerator can provide DVD quality video playback in VGA () resolution screens and support various movie formats such as MPEG-2/4 and Windows Media Video 9. This chip can play an image of MPEG4 or WMV at a speed of 30 frames per second!
Example: HP iPAQ RX4750 is HP this year's top model, is also a well-deserved machine, strong configuration and unfounded design concept, let it conquer countless people. The RX4750 uses Intel PXA 270 processor with a closing frequency of 624MHz, a memory of 128M ROM 64M RAM, and the user can use memory 135m. The 4-inch display has a VGA resolution of 640 * 480 and supports horizontal screen.
