Framework: Performance Measurement

Detailed Description

Defines Performance measurement and reporting interfaces.

In OpenVX, both vx_graph objects and vx_node objects track performance information. A client can query either object type using their respective vxQuery<Object> function with their attribute enumeration VX_<OBJECT>_ATTRIBUTE_PERFORMANCE along with a vx_perf_t structure to obtain the performance information.

vx_perf_t perf;
vxQueryNode(node, VX_NODE_ATTRIBUTE_PERFORMANCE, &perf, sizeof(perf));
