MULTITHREADED PROCESSOR AND DIGITAL TELEVISION SYSTEM

摘要

A processor system (10) is equipped with a physical processor (121), a context memory (127) for holding a TVID (140) that indicates that each of multiple threads is either a thread that belongs to host processing or a thread that belongs to media processing, a virtual monitor level OS for dividing multiple resources into a first resource correlated with a thread that belongs to host processing and a second resource correlated with a thread that belongs to media processing, a TLB (104) for allocating the first resource to a thread that belongs to host processing while allocating the second resource to a thread that belongs to media processing by referencing the TVID (140), a cache memory (109), an FPU allocation unit (108), and an execution unit (101) for executing the threads using the allocated resources.
