Abstract
The multi-threading changeover control apparatus of the present invention changes over threads in an information processing device in which a multi-threading method is used, and comprises a thread changeover request unit outputting a thread changeover request signal after a cache miss occurs in which an instruction to be fetched is not stored when the instruction is fetched or a thread execution priority order change request unit outputting a thread execution priority order change request signal.
Claims12
A thread changeover control apparatus, comprising:
- a thread changeover request device which changes over threads and which outputs a thread changeover request signal after a cache miss occurs in which an instruction to be fetched in the cache is not stored when the instruction is fetched in an information processing device in which a multi-threading method is use.
A thread changeover control apparatus, including:
- a priority order change request device which outputs a thread execution priority order change request signal after a cache miss occurs in which the instruction to be fetched is not stored in the cache when the instruction is fetched, in an information processing device using a multi-threading method.
A thread changeover method in an information processing device in which a multi-threading method is used, wherein
- a thread changeover request device outputs a thread changeover request signal after a cache miss has occurred in which an instruction to be fetched is not stored when the instruction is fetched.
A thread changeover method in an information processing device in which a multi-threading method is used, wherein
- a thread priority order change request device outputs a thread priority order change request signal after a cache miss has occurred in which an instruction to be fetched is not stored when the instruction is fetched.
