在手持式设备的应用中(包括智能电话、相机和 MP3 播放器)，用户大多考虑低功耗、

小尺寸，整个系统中除了处理器外，往往需要提供多种通信接口与存储器接口，用于实现对

硬盘、SD 卡、CF 卡以及 USB 的通信等，用 FPGA 来实现这些接口将会是一种理想的解决

方案。本方案采用 Actel 低功耗的 IGLOO 系列作为处理器(PXA270 或 ARM)的桥接器件和

设备控制器，不仅能够大大简化处理器设计的复杂度，而且 IGLOO 的超低功耗 (最小 5μ

W)以及超小封装(4mm*4mm)给手持式产品带来了前所未有的。 -In the application of handheld devices (including smart phone, camera and MP3 players), users are considering low-power,

Small size, the whole system in addition to the processor, usually need to provide various communication interface and storage interface, used to implement

Hard disk, SD card, CF card and USB communication, etc, to realize these interfaces with FPGA will be an ideal solution

Scheme. The scheme adopts Actel IGLOO of low power consumption PXA270 processor (series as a bridge or ARM) devices and

Equipment controller, can not only greatly simplified, and the complexity of the processor design IGLOO of low power consumption (minimum 5 mu

W) and small package (4mm 4mm*) for handheld product has brought an unprecedented.
