    Abstract: System, method, and circuitry for generating content for a programmable computing device based on user-selected memory regions. Contiguous regions that share memory access attributes are merged, interleaved contiguous regions that share at least one nested attribute are defined into combined regions, and remaining regions are defined as separate independent regions. A memory protection unit (MPU) region size closest to a size of each defined region is identified. If the start address of each region aligns with the address structure of the MPU region size, then those regions are assigned to MPU regions having the MPU region size; otherwise, another MPU size that aligns with the size of the regions is selected and those regions are assigned to MPU regions having that size. Content is generated to configure settings of MPU regions of the programmable computing device for the merged contiguous regions, the combined region, and the independent regions.

    Abstract: According to one aspect, a method adds an additional function to a computer program installed on a microcontroller, the computer program using a table configured to associate an identifier of the additional function with a pointer to a memory address. The method includes the microcontroller obtaining a compiled code of the additional function and an identifier of this additional function, the microcontroller recording the compiled code of the additional function in a section of a memory, and recording in memory a pointer in the table, the pointer being aimed at the address of the memory section in which the compiled code of the additional function is recorded, the pointer being associated in the table with the identifier of the additional function.

    IPC: G06F9/4401

    Abstract: System, method, and circuitry for generating content for a programmable computing device based on user-selected configuration information. A settings registry is generated based on the user's selections. The settings registry and the user selected configuration information is utilized to generate the content, such as code, data, parameters, settings, etc. When the content is provided to the programmable computing device, the content initializes, configures, or controls one or more software and hardware aspects of the programmable computing device, such as boot sequence configurations, internal peripheral configurations, states of the programmable computing device, transitions between states of the programmable computing device, etc., and various combinations thereof.
