Multi-processor command management in electronic components with multiple microcontrollers

摘要

In one embodiment, a computer-implemented method includes executing firmware including a command list configured to maintain commands executable by a host processor of a field-programmable unit. One or more of the commands define communications between the host processor and one or more back-end processors of the field-replaceable unit. The command list includes both periodic commands representing periodic processes and non-periodic commands representing non-periodic processes. Each command in the command list is set to one of active mode and inactive mode. Executing the firmware includes cycling through the command list, and executing, by the host processor, only the commands in the command list that are set to active mode while cycling through the command list.

1. A system comprising:
firmware of a field-replaceable unit, the firmware comprising a command list configured to maintain commands; a host processor of the field-replaceable unit configured to execute one or more of the commands in the command list; and one or more back-end processors of the field-replaceable unit, the one or more back-end processors being in communication with the host processor; wherein one or more of the commands in the command list define communications between the host processor and the one or more back-end processors of the field-replaceable unit; wherein the command list comprises both periodic commands representing periodic processes and non-periodic commands representing non-periodic processes; wherein each command in the command list is set to one of active mode and inactive mode; and wherein the host processor is further configured to: cycle through the command list; and execute only the commands in the command list that are set to active mode, while cycling through the command list.
