A relay drive circuit includes a power supply circuit for producing a constant voltage, an initial energization circuit for performing an initial energization such that a power supply provides an initial energizing voltage to a relay, a low-holding energization circuit for performing a low-holding energization such that the constant voltage provides a constant current to the relay after the initial energizattion. Due to the low-holding energization, the relay contact can be firmly held even when relay coil resistance changes. The constant voltage for performing the low-holding energization is lower than the power supply voltage so that power consumption and heat generation can be reduced.

Multi-threaded embedded processor using deterministic instruction memory to guarantee execution of pre-selected threads during blocking events

A multi-threaded embedded processor that includes an on-chip deterministic (e.g., scratch or locked cache) memory that persistently stores all instructions associated with one or more pre-selected high-use threads. The processor executes general (non-selected) threads by reading instructions from an inexpensive external memory, e.g., by way of an on-chip standard cache memory, or using other potentially slow, non-deterministic operation such as direct execution from that external memory that can cause the processor to stall while waiting for instructions to arrive. When a cache miss or other blocking event occurs during execution of a general thread, the processor switches to the pre-selected thread, whose execution with zero or minimal delay is guaranteed by the deterministic memory, thereby utilizing otherwise wasted processor cycles until the blocking event is complete.

Bandgap reference circuit and method

A circuit for generating a band gap reference voltage (VREF) includes circuitry (I3×7) for supplying a first current to a first conductor (NODE1) and a second current to a second conductor (NODE2). The first conductor is successively coupled to a plurality of diodes (Q0×16), respectively, in response to a digital signal (CTL-VBE) to cause the first current to successively flow into selected diodes. The second conductor is coupled to collectors of the diodes which are not presently coupled to the first conductor. The diodes are successively coupled to the first conductor so that the first current causes the diodes, respectively, to produce relatively large VBE voltages on the first conductor and the second current causes sets of the diodes not coupled to the first conductor to produce relatively small VBE voltages on the second conductor. The relatively large and small VBE voltages provide differential band gap charges (QCA-QCB) which are averaged to provide a stable band gap reference voltage (VREF).

System and Method for Information Handling System Data Redundancy

Flash memory integrated in a hard disk drive chassis maintains a back-up copy of data stored on the hard disk drive between back-ups of the hard disk drive data to separate storage devices. If the hard disk drive fails, the data on the flash memory provides a back-up of changes made since the previous hard disk drive back-up. When a back-up is made of data stored on the hard disk drive to an external storage device, the back-up on the flash memory device is erased to make room for subsequent back-up data. If back-up data stored on the flash memory approaches the capacity of the flash memory, a notice is provided to an end user that a back-up is needed.
