Abstract: An integrated circuit includes: a processor; a memory coupled to the processor; and a stack memory allocation controller coupled to the processor and the memory. The stack memory allocation controller has: a stack use manager configured to monitor activities of the processor. The stack memory allocation controller also has a virtual memory translator configured to: obtain a first mapping of pointers to a first sub-set of memory blocks of the memory assigned to a memory stack for a thread executed by the processor; and determine a second mapping of pointers to a second sub-set of memory blocks of the memory assigned to the memory stack and different than the first sub-set of memory blocks responsive to the monitored activities.

Abstract: Systems and methods for improved access point discoverability in multi-role multi-channel devices are described. When the multi-role multi-channel device leaves an AP role and then later returns to the AP role, such as when operating in another role, the multi-role multi-channel device sends a unicast probe response to the stations in a predetermined list. The unicast probe response is transmitted even without receiving a corresponding probe request. If one of the stations on the list is in the area and would like to connect to the AP role, it can complete the connection process using information in the response message.
