Abstract:
A graphics processing unit (GPU) includes an indexed streamout buffer. The indexed streamout buffer is configured to: receive vertex data of a primitive, and determine if any entries in a reuse table of the indexed streamout buffer reference the vertex data. Responsive to determining that an entry of in the reuse table references the vertex data, the buffer is further configured to: generate an index that references the vertex data, store the index in the buffer, and store a reference to the index in the reuse table. Responsive to determining that an entry does not reference the vertex data, the indexed streamout buffer is configured to: store the vertex data in the buffer, generate an index that references the vertex data, store the index in the buffer, and store a reference to the index in the reuse table.
