Abstract: In an operation scheduler adapted to schedule in an asynchronous contention-based system a first FIFO queue is adapted to store one trigger message or one operation request. A message router is coupled to the first FIFO queue and is adapted to route instructions to a second FIFO queue or a memory and locate in the memory the instructions of a suspended operation associated with a trigger message and authorize execution of the suspended operation. An arbitration unit is coupled to the second FIFO queue and to the memory, and is adapted to schedule the execution of instructions associated with a standalone non-preemptable operation during a period of time within which at least one operation of the first sequence is being suspended.

Abstract: Methods and systems are disclosed for multiple connection management for Bluetooth (BT) devices, and more particularly for BT Low Energy (BLE) devices, to multiple different bonded BT peer devices. A BT device database within a non-volatile memory (NVM) stores identification and persistent information for each bonded BT peer device. At power-on reset (PoR), only device identification information (DII) data, such as an address (ADDR) and an IRK (identity resolving key), for each bonded BT peer device is copied from the NVM to a volatile memory that is used for run-time operation. When a bonded BT peer device forms an active connection, it is identified using the DII data, and its persistent data is copied from NVM to volatile memory as run-time data. The BT device then communicates with the actively connected BT peer device at least in part using the run-time data for the actively connected BT peer device.

A message router is coupled to the first FIFO queue and is adapted to route instructions to a second FIFO queue or a memory and locate in the memory the instructions of a suspended operation associated with a trigger message and authorise execution of the suspended operation.
