摘要： Methods and apparatus for an inter-processor communication (IPC) link between two (or more) independently operable processors. In one aspect, the IPC protocol is based on a “shared” memory interface for run-time processing (i.e., the independently operable processors each share (either virtually or physically) a common memory interface). In another aspect, the IPC communication link is configured to support a host driven boot protocol used during a boot sequence to establish a basic communication path between the peripheral and the host processors. Various other embodiments described herein include sleep procedures (as defined separately for the host and peripheral processors), and error handling.

摘要： Methods and apparatus for a synchronized multi-directional transfer on an inter-processor communication (IPC) link. In one embodiment, the synchronized multi-directional transfer utilizes one or more buffers which are configured to accumulate data during a first state. The one or more buffers are further configured to transfer the accumulated data during a second state. Data is accumulated during a low power state where one or more processors are inactive, and the data transfer occurs during an operational state where the processors are active. Additionally, in some variants, the data transfer may be performed for currently available transfer resources, and halted until additional transfer resources are made available. In still other variants, one or more of the independently operable processors may execute traffic monitoring processes so as to optimize data throughput of the IPC link.

摘要： Methods and apparatus for isolation of sub-system resources (such as clocks, power, and reset) within independent domains. In one embodiment, each sub-system of a system has one or more dedicated power and clock domains that operate independent of other sub-system operation. For example, in an exemplary mobile device with cellular, WLAN and PAN connectivity, each such sub-system is connected to a common memory mapped bus function, yet can operate independently. The disclosed architecture advantageously both satisfies the power consumption limitations of mobile devices, and concurrently provides the benefits of memory mapped connectivity for high bandwidth applications on such mobile devices.

摘要： Methods and apparatus for controlled recovery of error information between two (or more) independently operable processors. The present disclosure provides solutions that preserve error information in the event of a fatal error, coordinate reset conditions between independently operable processors, and implement consistent frameworks for error information recovery across a range of potential fatal errors. In one exemplary embodiment, an applications processor (AP) and baseband processor (BB) implement an abort handler and power down handler sequence which enables error recovery over a wide range of crash scenarios. In one variant, assertion of signals between the AP and the BB enables the AP to reset the BB only after error recovery procedures have successfully completed.

摘要： Methods and apparatus for registering and handling access violations of host memory. In one embodiment, a peripheral processor receives one or more window registers defining an extent of address space accessible from a host processor; responsive to an attempt to access an extent of address space outside of the extent of accessible address space, generates an error message; stores the error message within a violation register; and resumes operation of the peripheral processor upon clearance of the stored error message.

摘要： A method includes inter-chip data communications between a power-managed integrated circuit (IC) and a peer IC. The peer IC generates a data frame and prepends a discardable preamble of a predefined size to a payload of the data frame. The predefined size is a size not less than a size of data discarded by the power-managed IC upon the power-managed IC receiving a data frame while in a low-power state. The peer IC transmits the data frame to the power-managed IC. The power-managed IC, while in a low-power state, may receive the data frame from the peer IC and in response to receiving the data frame, begin exiting the low-power state. The power-managed IC, while exiting the low-power state, may discard a portion of the data frame such as for example, some or all of the discardable preamble, without discarding payload.
