A video hardware engine which support dynamic frame padding is disclosed. The video hardware engine includes an external memory. The external memory stores a reference frame. The reference frame includes a plurality of reference pixels. A motion estimation (ME) engine receives a current LCU (largest coding unit), and defines a search area around the current LCU for motion estimation. The ME engine receives a set of reference pixels corresponding to the current LCU. The set of reference pixels of the plurality of reference pixels are received from the external memory. The ME engine pads a set of duplicate pixels along an edge of the reference frame when a part area of the search area is outside the reference frame.

Multi-domain clock generation with skew compensation is based on free-running counters in each of the multiple clock domains. Multi-domain clock generation circuitry provides at least first and second domain clocks generated with randomization, each based on an input clock with an input clock frequency, the domain clocks having a relative clock skew that is varied over time in magnitude and direction. A first circuit in a first clock domain, configured for operation with the first domain clock, includes a first free-running counter with a pre-defined first selected roll-over count, to generate a first free-running count (N(k)) based on the first domain clock. A second circuit in a second clock domain is configured for operation with the second domain clock, and includes a second free-running counter with a pre-defined second selected roll-over count, to generate a second free-running count (N(k)) based on the second domain clock.
