TC275 TC1.6P 锁步核(Checker)的功耗是非锁步核的百分之多少呀?

锁步核对于功耗没影响吧,只是个镜像核。

锁步核有功耗的,它也执行指令,做功了自然就有功耗。根据“Infineon-TC26xBC-DataSheet-v01_00-EN.pdf”单个锁步核的最大电流32mA,VDD最大电压1.43 V,算出来最大功耗45.76mW。

那我的理解是,TC275逻辑上还是三个核,只是core0核core1具有lockstep的功能,此功能可以通过BMI使能或禁止,而cold reset直接默认将其关闭。所以开启锁步功能的核,比不开启时功耗应该大些。

是的,开启锁步核后,会有一个功耗方面的增量。
