Intel® Iris™ Graphics Extension for instant access for 4th Generation Intel® Core™ processors allows direct access to memory allocated for the GPU. The extension provides a mechanism for specifying which buffers will be shared and locking the memory for reading and writing from CPU side code. This sample demonstrates how to properly access the memory from the CPU to maintain performance with sample code for computing the tiled addressing scheme.
