Abstract: One embodiment of the present invention sets forth a technique for translating application programs written using a parallel programming model for execution on multi-core graphics processing unit (GPU) for execution by general purpose central processing unit (CPU). Portions of the application program that rely on specific features of the multi-core GPU are converted by a translator for execution by a general purpose CPU. The application program is partitioned into regions of synchronization independent instructions. The instructions are classified as convergent or divergent and divergent memory references that are shared between regions are replicated. Thread loops are inserted to ensure correct sharing of memory between various threads during execution by the general purpose CPU.

Abstract: A partition unit that includes a cache for storing both data and error-correcting code (ECC) checkbits associated with the data is disclosed. When a read command corresponding to particular data stored in a memory unit results in a cache miss, the partition unit transmits a read request to the memory unit to fetch the data and store the data in the cache. The partition unit checks the cache to determine if ECC checkbits associated with the data are stored in the cache and, if the ECC checkbits are not in the cache, the partition unit transmits a read request to the memory unit to fetch the ECC checkbits and store the ECC checkbits in the cache. The ECC checkbits and the data may then be compared to determine the reliability of the data using an error-correcting scheme such as SEC-DED (i.e., single error-correcting, double error-detecting).

Abstract: A device including a touch screen display may be configured to selectively filter touch input. The device may receive a plurality of touch events. The device may determine whether the touch events correspond to a scaling gesture.

The smoothing filter may be a Kalman based filter. The device may perform a scaling operation using the filtered data. When the device determines that the touch events do not correspond to a scaling gesture, to reduce latency, the smoothing filter may not be applied.

Abstract: One embodiment of the present invention sets forth a technique for generating a batch clip state stored in clip state machine (CSM) associated with a batch of vertices. Per-vertex clip state is generated for each vertex in the batch of vertices based on the position of each vertex relative to each clip plane. For a given vertex, per-vertex clip state indicates whether the vertex is inside or outside each of the one or more clip planes. The per-vertex clip states of all the vertices in the batch of vertices are coalesced into a batch clip state by determining whether each vertex in the batch of vertices is inside every clip plane, each vertex is outside at least one clip plane or neither. The batch clip state is stored in the CSM associated with the thread group that processes the batch of vertices that can be accessed by further stages of the graphics pipeline.
