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 。
