Memory caching for force feedback effects

摘要

Methods and apparatus for efficient management of memory in a force feedback system including a host computer and a force feedback device. A representation of device memory is maintained on the host computer to allow the host computer knowledge and control over storage and force effects in the device memory. A host cache for force effects is provided to allow almost unlimited numbers of force effects to be created for the device, where any force effects not able to fit in device memory are stored in the host cache.
