Boot : The TMS320DM643x DMP 通过配置既可以从异步 EMIFA/NOR直接启动,也可从内部 Boot ROM 启动 不管哪种启动:C64x+ CPU 立即从Reset返回,从下面的地址开始执行: EMIFA Chip Select Space 2 (4200 0000h) Internal Boot Rom (0010 0000h)
EMIF: 32位DDR2 SDRAM 控制器 (256M地址空间) 8位异步 EMIFA (64M地址空间) 4个 高达32M的片选空间 8位数据宽度
EDMA:通道控制器,传输控制器 特点: 3传输规模 传输灵活
引脚复用:通过PINMUX0和PINMUX1进行配置 本贴地址:http://www.hellodsp.com/bbs/viewthread.php?tid=7365
