RESOURCE ALLOCATOR, MULTICORE PROCESSOR AND RESOURCE ALLOCATION METHOD

摘要

A resource allocator (10) for controlling a processor (20) having at least two cores (21, 22) comprises an apparatus (11) for starting (110) a first process (31) on a first core (21) of the processor (20), an apparatus (12) for starting (120) a second process (32) on a second core (22) of the processor (20) and an apparatus (14) for interrupting (140) or terminating the first process (31). The resource allocator (10) also comprises an apparatus (13) for receiving (130') a resource request (51) when the second process (32) is awaiting release of a resource (44, SL1–3) that cannot be used by the two cores (21, 22) simultaneously without reciprocal influencing of the two processes (31, 32). Furthermore, the invention relates to a multicore processor (20) that comprises a resource allocator (10) according to the invention and to a corresponding resource allocation method (100).
