Abstract: In one set of embodiments, a temperature measurement system may include an analog to digital converter (ADC) to produce digital temperature readings according to a difference base-emitter voltage (ΔVBE) developed across a PN-junction. A clock generating circuit may be configured to provide a sampling clock used by the ADC, which in some embodiments may be a delta-sigma ADC, in performing the conversions. The clock generating circuit may be configured to change the frequency of the sampling clock a specified number of times within each one of the one or more conversion cycles to reduce an error component in the temperature measurement, where the error component is produced by an interfering signal, such as an electromagnetic interference (EMI) signal being coherent with the sampling clock, and/or a noise residing on the voltage supply and also being coherent with the sampling clock.

Abstract: A temperature sensor circuit and system providing accurate readings using a temperature diode whose ideality factor may fall within a determined range. In one set of embodiments a change in diode junction voltage (ΔVBE) proportional to the temperature of the diode is captured and provided to an ADC, which may perform required signal conditioning functions on ΔVBE, and provide a numeric value output corresponding to the temperature of the diode. Errors in the measured temperature that might result from using diodes with ideality factors that differ from an expected ideality factor may be eliminated by programming the system to account for differing ideality factors. The gain of the temperature sensor may be matched to the ideality factor of the temperature diode by using an accurate, highly temperature stable reference voltage of the ADC to set the gain of the temperature measurement system. The reference voltage may have a trim capability to change the gain setting voltage by a digital address comprising a determined number of bits, with the programmable range for the reference voltage corresponding to a determined range of ideality factors.

Abstract: An apparatus and method for handling an interrupt are disclosed. In one embodiment, a processor may receive an interrupt request corresponding to a particular interrupt. The particular interrupt may be one of a group of interrupts. Responsive to receiving the interrupt request, the processor may substitute a vector corresponding to the group of interrupts with a vector corresponding to the particular interrupt. Responsive to the substitution, the processor may then jump to a service routine corresponding to the particular interrupt. Execution of the service routine may resolve the condition which initially caused the interrupt request.

Abstract: In various embodiments, icons, specific to a type of memory card (e.g., a flash memory card) inserted into a card reader may be displayed. In some embodiments, the card reader may be electrically connected to the host controller each time a memory card is inserted into the card reader. In various embodiments, different device identifications may be reported as if the card reader were actually several different card readers each dedicated to a different memory card type. A registry of an operating system may be preloaded with a different icon for each of the different card reader types. An icon may be displayed on a display specific to the type of memory card inserted. When the memory card is removed, the card reader may be electrically disconnected and the displayed icon may be removed or replaced.

Abstract: In one embodiment, the invention comprises a flash-media controller used for writing new data from an external system to a local flash-memory device. The newly written data may replace old data previously written to the flash-memory device, and may be written directly to unused locations within the flash-memory device. The flash-media controller may comprise a table of block descriptors and sector descriptors used to track specified characteristics of each block and sector of the flash-memory device, thereby allowing for write sequences to non-contiguous sectors within a block. Accordingly, copy operations may be deferred under the expectation that they will eventually become unnecessary, thereby designating old data as having become stale. Once all data within a block has been designated as being stale, the block may be marked as unused and may be made available for subsequent write operations, thereby providing fast write access to the flash-memory device, and significantly reducing the number of required copy operations during data transfer to the flash-memory device.

Abstract translation: 在一个实施例中，本发明包括用于将新数据从外部系统写入本地闪存设备的闪存介质控制器。 新写入的数据可以替换先前写入闪存设备的旧数据，并且可以直接写入闪存设备内的未使用的位置。 闪存介质控制器可以包括用于跟踪闪存设备的每个块和扇区的指定特性的块描述符和扇区描述符的表，从而允许对块内的非连续扇区的写入序列。 因此，复制操作可能会延迟，期望它们最终将变得不必要，从而将旧数据指定为过时的。 一旦块中的所有数据被指定为过期，则该块可被标记为未使用，并且可以使其可用于随后的写入操作，从而提供对闪存设备的快速写入访问，并且显着地减少所需拷贝的数量 数据传输到闪存设备时的操作。

The control logic is configured to generate the duty cycle value to have a piecewise linear relationship with temperature such that at least two of a plurality of linear segments defined by the piecewise linear relationship have different slopes. In some embodiments, the piecewise linear relationship may be continuous.

Abstract: A temperature measurement device may be implemented by coupling a PN-junction, which may be comprised in a diode, to an analog-to-digital converter (ADC) that comprises an integrator. Different currents may be successively applied to the diode, resulting in different VBE values across the diode. The ΔVBE values thus obtained may be successively integrated. Appropriate values for the different currents may be determined based on a set of mathematical equations, each equation relating the VBE value to the temperature of the diode, the current applied to the diode and parasitic series resistance associated with the diode. When the current sources with the appropriate values are sequentially applied to the diode and the resulting diode voltage differences are integrated by the integrator comprised in the ADC, the error in the temperature measurement caused by series resistance is canceled in the ADC, and an accurate temperature reading of the diode is obtained from the output of the ADC.

Abstract: A method and apparatus for operating a portable computer configured for docking to a docking station is disclosed. In one embodiment, a portable computer system includes a docking interface having a bus switch and a bus monitoring circuit, and a bus coupled to the docking interface. With the computer coupled to a docking station, the bus switch, when closed, may couple the bus to a peripheral interface in the docking station. The bus switch may close responsive to docking, thereby completing the electrical coupling of the bus to the peripheral interface in the docking station. The portable computer being docked to the docking station, the bus monitoring circuit may monitor the bus cycles occurring on the bus and identify trusted read and/or write cycles. During trusted bus cycles the monitoring circuit may operate to open the bus switch thereby preventing information transmitted during the trusted cycles to be accessible outside of the portable computer system, even with the portable computer system remaining docked to the docking station. The monitoring circuit may also operate to close the bus switch in response to a currently occurring trusted bus cycle being interrupted, aborted and/or completed.
