Abstract
Data processing apparatus includes a data path having a path delay, from a source latch point to a destination latch point, of greater than one clock cycle. For an n-cycle path, where the path delay is between n- 1 and n clock cycles, data is latched into the source latch point at least n clock cycles in advance of the cycle on which it is needed at the destination latch point. The data and gating signals along the data path are held glitch-free in the source latch point until after the clock cycle on which the data is used in the destination latch point.
