Description
本发明涉及电子领域,尤其涉及一种电子芯片中的功率分配方法及***。
芯片,英文为Chip;芯片组为Chipset。芯片一般是指集成电路的载体,也是集成电路经过设计、制造、封装、测试后的结果,通常是一个可以立即使用的独立的整体。“芯片”和“集成电路”这两个词经常混着使用,比如在大家平常讨论话题中,集成电路设计和芯片设计说的是一个意思,芯片行业、集成电路行业、IC行业往往也是一个意思。实际上,这两个词有联系,也有区别。集成电路实体往往要以芯片的形式存在,因为狭义的集成电路,是强调电路本身,比如简单到只有五个元件连接在一起形成的相移振荡器,当它还在图纸上呈现的时候,我们也可以叫它集成电路,当我们要拿这个小集成电路来应用的时候,那它必须以独立的一块实物,或者嵌入到更大的集成电路中,依托芯片来发挥他的作用;集成电路更着重电路的设计和布局布线,芯片更强调电路的集成、生产和封装。而广义的集成电路,当涉及到行业(区别于其他行业)时,也可以包含芯片相关的各种含义。
