by finnce MOTO MPx220 與Dopod 575/585 之內(nèi)核CPU的比較( 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多了下面的幾個內(nèi)容:
Security Acceleration in Hardware 硬件安全加速
2-Mb ISRAM 傳說中的內(nèi)部RAM , 據(jù)說可以增強(qiáng)多媒體性能
Memory Traffic Controller (TC) 內(nèi)存流量控制
16-bit EMIFS external memory interface 16-bit EMIFF external memory interface 【by finnce MOTO MPx220 與Dopod 575/585 之內(nèi)核CPU的比較】結(jié)論:可以看出TI是有意區(qū)分兩種不同定位的產(chǎn)品的 , 但是由于總的來說都屬于無線應(yīng)用方案 , 又是采用相同的核心子系統(tǒng) , 所以兩種產(chǎn)品的表現(xiàn)較為接近 。
