Your 'L0' cache would be the registers.  Opteron, for example, has just over
21Kb of total register space (most is not visible to programmers).

On the P4 and Itanium, L1 access takes only 2 clock cycles.  It's practically
impossible to get faster than that.  I think it takes 3 cycles on Athlons, which
is still very fast.
