    摘要: A voltage scaling system can scale a supply voltage while preventing processor access of system components that are rendered unstable from the scaling. A processor receives an instruction to scale a system supply voltage to a target supply voltage. The processor executes the instruction and enters into a sleep mode. The processor can send, to a controller that saves power, an indication that the processor is in the sleep mode. When the processor is in the sleep mode, the processor becomes inactive and cannot access any components, e.g., Flash memory data, of the voltage scaling system. The controller can configure a voltage regulator to scale the system supply voltage to the target supply voltage. Once the target supply voltage is reached, the voltage regulator sends an interrupt to the processor, thereby waking up the processor from the sleep mode.

    摘要: The disclosure relates to a reverse Polish notation processing device making it possible to execute a set of instructions and implementing management of a stack whose size is variable. The device includes a storage device including a random access memory; a device for managing a stack pointer, which is a physical address, in said random access memory, associated with a reference stage of the stack; and a device for managing reference element pointer(s), which is a physical address, in said random access memory, associated with one reference element among elements of a given table contained in the stack. The processing device can execute at least one table-handling instruction with respect to the reference element pointer(s).

    摘要: A microcontroller system includes a main voltage regulator and a low power voltage regulator having a static current consumption less than the static current consumption of the main voltage regulator. A power state controller enables the low power voltage regulator during a power saving mode. On exiting the power saving mode, the power state controller enables the main voltage regulator and disables the low power voltage regulator after determining that the main voltage regulator is ready. The switching circuitry can be asynchronous.

    摘要: A voltage scaling system can scale a supply voltage while preventing a processor from communicating with first system components that are rendered unstable from the scaling. On the other hand, the voltage scaling system allows second system components that are stable during the scaling to communicate with the processor. A processor scales a system supply voltage to a target supply voltage. The processor halts operations of the first system components and executes the instruction. When the first system components are halted, the processor cannot access the first system components. The second system components can continue operating during the scaling. A controller that saves power can configure a voltage regulator to scale the system supply voltage to the target supply voltage. Once the target supply voltage is reached, the voltage regulator sends an indication to a power management unit, after which the first system components continue to operate.

    摘要: A microcontroller includes first and second modules. The first module can operate in a mode that causes interference with operation of the second module. A control circuit on the first module and a control circuit on the second module coordinate operation of the first and second modules to prevent the interference from causing the second module to function incorrectly.
