  • Patent number: 8341382
    Abstract: A microcontroller using an optimized buffer replacement strategy comprises a memory configured to store instructions, a processor configured to execute said program instructions, and a memory accelerator operatively coupled between the processor and the memory. The memory accelerator is configured to receive an information request and overwrite the buffer from which the prefetch was initiated with the requested information when the request is fulfilled by a previously initiated prefetch operation.

  • Patent number: 8065512
    Abstract: One embodiment of the present application includes a microcontroller (30) that has an embedded memory (46), a programmable processor (32), and a test interface (34). The memory (46) is accessible through the test interface (34). In response to resetting this microcontroller (30), a counter is started and the test interface (34) is initially set to a disabled state while an initiation program is executed. The test interface (34) is changed to an enabled state—such that access to the embedded memory (46) is permitted through it—when the counter reaches a predefined value unless the microcontroller (30) executes programming code before the predefined value is reached to provide the disabled state during subsequent microcontroller (30) operation.
