by finnce MOTO MPx220 与Dopod 575/585 之内核CPU的比较( 二 )


Application Subsystem
Supports leading operating systems DMA with 4 physical and 17 logical channels and a dedicated 2D graphics engine USB On-the-Go (OTG) Two SD/MMC/SDIO ports Two high-speed 3.68 MHz UARTs I2C controller Two high-speed 3.68 MHz UARTs uWire CompactFlash Parallel and compact camera ports Enhanced Debug Trace (ETM) for debug Fast IrDA (FIR) SPI LCD controller 54-Mbps interface to WLAN 802.11a/b/g Comprehensive memory controller for interfaces to: 128 MB of mobile SDRAM and mobile DDR 256 MB Flash (for burst, programmable NOR flash)值得注意的是 , 1611多了下面的几个内容:
Security Acceleration in Hardware 硬件安全加速
2-Mb ISRAM 传说中的内部RAM , 据说可以增强多媒体性能
Memory Traffic Controller (TC) 内存流量控制
16-bit EMIFS external memory interface 16-bit EMIFF external memory interface 【by finnce MOTO MPx220 与Dopod 575/585 之内核CPU的比较】结论:可以看出TI是有意区分两种不同定位的产品的 , 但是由于总的来说都属于无线应用方案 , 又是采用相同的核心子系统 , 所以两种产品的表现较为接近 。
