2008-03-25: The 29 GHz Barrier
Category: General
Posted by: afeldstein
No legal SPARC-V9 implementation can be clocked faster than 29 GHz. We know that the TICK register represents CPU clock cycles. But IMPL. DEP. #105 states that "TICK.counter ... must be able to count for at least 10 years without overflowing." If you do the math, you'll see that that imposes a 29 GHz limit on clock rate.
What if I want a faster SPARC? Is anyone working on SPARC-V10?
