MANHASSET, N.Y. ATI Technologies (Markham, Ontario) has developed a memory technology that enables visual processors to use system memory for graphics processing, thus lessening dependence on graphics memory and lowering system costs.
Called HyperMemory, the technology uses the high-speed bi-directional data transfer capabilities of PCI Express to store and access graphics data in system memory.
Under previous interconnect standards, the data transfer between the visual processor and the CPU was not fast enough for real-time graphics applications, so graphics cards have shipped with up to 256 MB of dedicated graphics memory to store textures and rendering data required by the graphics processor.
According to ATI, HyperMemory makes it possible to deliver cards with less on-board memory and instead use system memory to handle the graphics storage requirements.
HyperMemory uses intelligent memory allocation algorithms to optimize the use of available local memory and ensure critical components are placed in fast local memory when required. Optimal assignment of data to local or system storage is determined dynamically to ensure the best user experience.
The technology also increases the performance of system bus data transfers, speeding accessing of system memory, the company said.
Graphics cards featuring HyperMemory technology will be announced later this year.
