International Classification:

G06F 12/00

US Classification:

711170, 711102, 711104, 711173

Abstract:

An internal memory uses a resource identifier to identify which functional program from an external memory is to be loaded into an overlay space of the internal memory. In executing a program statement of a main program to perform a particular functional operation without identifying a corresponding functional program, a prelude stored in a prelude space of the internal memory provides a resource identifier for the functional operation. The resource identifier identifies a corresponding functional program to perform the particular functional operation and the identified functional program is then loaded into the overlay space to be executed.

International Classification:

G06F 15/177

US Classification:

713 2, 713 1

Abstract:

A method for “booting up” a multiple function device that first involves determining a configuration state of the multiple function device. Based on the configuration state, a functional mode is selected from a number of functional modes. A functional algorithm associated with the selected functional modes is accessed from memory. The functional algorithm is then examined to determine if the algorithm is executable. When the functional algorithm is not executable and the multiple function device is operable coupled to a host, a functional algorithm is downloaded from the host. Otherwise, the device may time-out and is powered down.

International Classification:

G06F 9/44

US Classification:

711170, 717140, 717157, 717159

Abstract:

An internal memory uses a resource identifier and an entry point to identify which functional program from an external memory is to be loaded into one of a plurality of overlay spaces established in the internal memory. In executing a program statement, the resource identifier identifies a corresponding functional program to perform a particular functional operation and the identified functional program is then loaded into an overlay space specified by the entry point. The functional program is then executed in the overlay space.

US Classification:

713 2, 713 1, 714 36

Abstract:

A method for “booting up” a multiple function device that involves first detecting the activation of the multiple function device. A 1boot algorithm, retrieved from read-only memory, is executed to identify the location of a 2boot algorithm. The 2boot algorithm, retrieved from a specified location based on the booting inputs, is verified for executability. When the 2boot algorithm is executable, it is executed to retrieve the functional algorithms that configure the multiple function device in the desired configuration. When the 2boot algorithm is not executable, and the multiple function device is operably coupled to a host, the correct functional algorithm or a default functional algorithm is downloaded and executed to configure the multiple function device. When an executable functional algorithm cannot be retrieved from memory or the host, the multiple function device powers down after a predetermined amount of time.

Abstract:

A semiconductor device includes an adjustable current source that is coupled to an external battery. The semiconductor device includes a feedback control module that is responsive to a voltage level at the external battery. The feedback control module also has an output that is directed to control the current supplied by the adjustable current source. Also, the feedback control module can selectively provide a signal to periodically and temporarily turn off the current supplied by the adjustable current source. A voltage at the external battery is measured during a time period when the current is turned on and during a time period when the current is turned off. While the current is turned off, the feedback control module can measure the external battery voltage so that it can be compared to the battery voltage while the adjustable current source is on.

US Classification:

710 14, 713320

Abstract:

The disclosure is directed to a computational device including functional circuitry, a transceiver interface that is accessible to the functional circuitry, and a universal serial bus transceiver that is accessible to the transceiver interface and that is configured to couple to a universal serial bus compatible media. The transceiver interface is configured to provide a first set of configuration data including a first power setting to a host device via the universal serial bus transceiver. The universal serial bus transceiver is configured to electrically disconnect from and electrically reconnect to the universal serial bus media in response to a suspension signal. The transceiver interface is also configured to provide a second set of configuration data including a second power setting after electrically reconnecting.
