摘要: Following a restart or a reboot of a system that includes a multi-core processor, the multi-core processor may assign one of the cores as a boot strap processor (BSP). Initialization logic may detect a state of each of the plurality of processing cores as active or inactive. The initialization logic may detect an attribute of each of the plurality of processing cores as eligible to be assigned as a BSP or as ineligible to be assigned as the BSP. The initialization logic may detect a last processing core of the plurality of processing cores in the interconnect that is an active processing core based at least in part on the state and is eligible to be assigned as the BSP based at least in part on the attribute. In various embodiments, the initialization information may assign the last processing core as the BSP.

摘要: This disclosure is directed to use of shared initialization and configuration vectors, which are delivered to processing cores in a multi-core processor using packets. An initialization core may include reset logic that may read initialization and configuration vectors from a centralized storage location, which may be on a die containing the processing cores (e.g., a fuse, etc.), off the die (e.g., in volatile memory, flash memory, etc.), or a combination of both. The initialization core may then generate packets to transmit the initialization and configuration vectors to processing cores that await initialization (e.g., following a reset). In some instances, the initialization and configuration vector information may be shared by two or more cores of a same type.

摘要: This disclosure is directed to performing a controlled reset of one or more cores while maintaining operation of at least one other core in a multi-core processor. An initialization core may include reset logic that may detect a problematic core or core that is unresponsive or otherwise not operating properly. The initialization core may generate a packet that enables communication with the problematic core. The initialization core may send a reset packet to the problematic core to instruct the problematic core to perform a reset.

摘要: An initialization core may include reset logic that may detect a global reset signal (GRS). The initialization core may generate one or more packets that enable communication with the cores. The initialization core may send reset packets to each of the cores that instruct the cores to perform a reset. In some embodiments, the reset command may power-off the cores. The initialization core may then transmit unreset packets to each of the cores that instruct the cores to perform an unreset and power-on the cores. In some embodiments, the cores may resume operation automatically without receipt of the unreset packet. The transmission of the packets may be staggered (staged) to control the power-on of the processor and enable the processor unit to more slowly increase its power state.
