便携式医疗设备的特殊性决定了它们应该是对用户友好的、必须工作在无菌环境下,并且空间占用小、耗能低。 同时,便携式医疗设备还需要足够的计算能力以便处理医疗数据,能够连接到无线或有线接口以便记录和发送数据。从设计人员的角度考虑,上述需求需要低功耗的单片机(MCU)和数字信号控制器(Digital Signal Controller,DSC)。 正是有了嵌入式处理器,设计人员才有可能设...[详细]
据国外媒体报道,英特尔将处理器价格最高下调31%,但降价整体来说是有限的。 根据英特尔7月20日的新定价单来看,Core 2 Duo E8500(3.16GHz)价格降幅最高,从266美元下调至183美元,降幅达31%;Core 2 Duo E7200 (2.53GHz)次之,从133美元下调至113美元,降幅15%。 其他降价处理器还有四核Q6600(2.4GHz),从224美...[详细]
