USB2.0 (High Speed): 480Mbps半双工, 二线制总线, 0.5A
USB3.0 (Super Speed): 5Gbps全双工, 对偶单纯形四线制差分信号线, 1A. USB 3.0 并没有采用设备轮询,而是采用中断驱动协议。
因此,在有中断请求数据传输之前,待机设备并不耗电。
简而言之,USB 3.0支持待机、休眠和暂停等状态。

ICV
ICV: inventory carry value,简称成本=DM+MOH+DL+VOH
ICV有很多细分,有frozen cost,MMICV,TP,所以如果要查ICV,需要先告诉财务你要查的具体是frozen cost,还是MMICV,还是TP.
frozen cost: Oracle系统里rollup出来的成本
MMICV: Marketmaker系统rollup出来的成本
TP是transfer price,是GE内部公司间往来的价格
ICV的组成:
无论是frozen cost还是MMICV,都是由五部分组成的
ICV=DM+MOH+DL+OSP+VOH
DM:direct material是直接材料成本
MOH:material overhead是运费
DL:direct labor是直接人工
OSP:outside sourcing price是外包成本
VOH:variable overhead是其他生产成本,如包装,报废和工具等
对buy件而言,DM就是供应商报价,MOH是根据每个inventory org的MOH rate算出来的,DL,OSP,VOH都是0 对make件而言,DM是BOM里所有buy件的DM的和,MOH是根据MOH rate算出来的,DL是根据labor hour和DL rate算出来的,VOH是根据DL和VOH rate算出来的
MOH=DM*MOH rate
DL=labor hour*DL rate
VOH=DL*VOH rate。
