    Abstract: In an example, a method includes storing code for a first central processing unit (CPU) executing a first application in a first region of a memory, and storing code for a second CPU executing a second application in a second region of the memory. The method includes storing shared code for the first CPU and the second CPU in a third region of the memory. The method includes storing read-write data for the first CPU in a fourth region of the memory and storing read-write data for the second CPU in a fifth region of the memory. The method includes translating a first address from a first unique address space for the first CPU to a shared address space in the third region, and translating a second address from a second unique address space for the second CPU to the shared address space in the third region.

    Abstract: A microcontroller is provided and comprises a central repository, a processing device, and a firewall. Rule repository memory in the central repository stores one or more access rules defining an access permission of a software context to one or more target resources of the microcontroller. The firewall receives a bus transaction initiated based on an instruction and determines whether any access rule stored in memory of the firewall defines the access permission of the software context to a destination resource. If no access rule stored in the firewall memory defines the access permission, the firewall communicates a miss query condition to the central repository. The central repository searches the rule repository memory for an access rule defining the access permission of the software context to the destination resource, and if a related access rule is found, the related access rule is stored in the firewall memory.

    Abstract: Various examples disclosed herein relate to allocation of code and data of application software among memory of a microcontroller unit (MCU), and more particularly to allocating portions of the application software to random access memory or flash memory of an MCU based on information associated with of each portion of the application software. A method is provided herein that comprises instructing an MCU to execute an application software. The method further comprises obtaining information indicative of a performance of portions of the application software on the MCU and capacity requirements of the portions of the application software, and designating, based on the information, each of the portions of the application software for execution from either a first memory or a second memory when deployed to one or more MCUs.

    Abstract: An electronic device, comprising: a first component configured to transmit a first set of data to a second component by providing a first memory request specifying the first set of data for and an input memory address, and a transaction tracking unit coupled to a first transport interface, the transaction tracking unit configured to: receive the first memory request; transmit a second memory request that specifies at least a first portion of the first set of data, via the first transport interface, to the second component; receive a response to the second memory request from the second component; determine that the response corresponds to the second memory request; and provide, to the first component, an output response based on the received response to the second memory request.
