TESSELLATION DEVICE INCLUDING CACHE, METHOD THEREOF, AND SYSTEM INCLUDING THE TESSELLATION DEVICE

摘要

The present invention relates to a tessellation device including a cache, to an operation method thereof, and to a system including the tessellation device. A tessellation method includes the steps of: determining whether a previous tag the same as a current tag of a current patch is stored in the cache; and transmitting a previous tessellation pattern corresponding to the previous tag stored in the cache to a domain shader when hitting the cache. When the cache is missed, the method includes the steps of: generating the current tessellation pattern corresponding to the current patch by using tessellation and transmitting the generated current tessellation pattern to the domain shader; and storing the generated current tessellation pattern in the cache. The present invention provides the tessellation device, the operation method thereof, and to the system including the tessellation device for selectively skipping the operation of the tessellation device by using the cache.
