Examples for performing static timing analysis on clocked circuits are described. An example static timing analysis computing device includes a logic device, and a storage device holding instructions executable by the logic device, the instructions including instructions executable to receive an input representative of one or more delays within a signal path in a cross-domain circuit, the cross-domain circuit configured to transfer data between a first domain having a first clock and a second domain having a second clock asynchronous with the first clock, receive an input representative of a static timing analysis constraint to be met by a signal traveling the signal path in the cross-domain circuit, apply the constraint in a static timing analysis of the signal path in the cross-domain circuit, and output a result based upon applying the static timing analysis constraint.

In a motion compensation engine, a number of blocks are provided for re-ordering motion vector (MV) reference positions prior to fetch. An MV Sort & Group block outputs MVs one at a time to a Decomposer block. The Decomposer block takes each MV and decomposes it into a series of DRAM read commands consisting of DRAM addresses. This rectangular region is divided into pixel words, which correspond to addressable DRAM words. The addresses are then sent to an Overlap Remover block, which comprises a bitmap corresponding to the DRAM addresses sent to it from the Decomposer block. Before a group is received, the bitmap is cleared by setting all coordinates to '0'. Each address received causes the Overlap Remover to set a bit to '1' in the bitmap which corresponds to a relative (x,y) coordinate within a small bounded rectangular region. Addresses received within a group, which are the same as previous addresses, are overlapping addresses and the corresponding bit will simply remain set to &#x201c;1&#x201d;.
