Timing is everything when it comes to wringing the most out of a PC.

TimeLab Corp., a 4-year-old Andover, Mass., startup founded by researchers from Zoran Corp., a maker of chips for products such as DVD drives, is expected to later this month unveil TotalClock, a digital clock chip it says replaces the traditional timing gear for PCs—chips called phase-locked loops—and fosters improvements by better regulating chips’ speeds.

The startup says TotalClock can regulate the clock speed of PC processors and other components, such as buses that shuttle data and memory, on the fly.

Its goal is to replace phase-locked loop chips with the TotalClock chip, which it says can better regulate the speed of PC hardware and thus boost desktops’ performance and or extend battery life in notebooks.

Although they’re given little thought by anyone but PC makers or enthusiasts, PLLs (phase-locked loops) have a huge effect on the performance of PCs, one analyst said.
