Abstract: A method is provided for monitoring an execution of a selected program code portion stored in a memory address range between a start address and an end address. The method includes starting a timing when a program counter points to the start address of the selected program code portion. Current values of the program counter are compared with a set of target addresses specific to the selected program code portion including the end address of the selected program code portion. The timing is stopped when the program counter points to the end address of the selected program code portion. An error signal is generated in response to the timing duration being outside a nominal duration range specific to the selected program code portion.

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.

Abstract: A method can be used for verifying an execution of a compiled software program stored in a program memory of a processor and executed by the processor. A write operation includes assigning a destination address in a register of the processor and writing a datum at a location pointed to by the destination address contained in the register. A verification operation includes reassigning the same destination address in the same register, reading the datum contained at the location pointed to by the destination address contained in the register after the reassignment, and comparing the read datum and the written datum.

Abstract: In an embodiment a current limiting circuit includes a circuit configured to detect when an input or output current of a DC to DC converter exceeds or falls below a threshold and a controller configured to store a first value representative of a level of an output voltage of the DC to DC converter in response to the input or output current exceeding or falling below a first threshold, store a second value representative of the level of the output voltage in response to the input or output current falling below a further threshold and modify a control signal based on the first and second values, wherein the control signal is modified based on the first and second values so that the control signal brings the output voltage to an intermediate voltage level between the level of the output voltage represented by the first value and the level of the output voltage represented by the second value.
