    摘要： Method and apparatus for calibration of a low frequency oscillator in a processor based system. A method for calibrating an on-chip non-precision oscillator. An on-chip precision oscillator is provided having a known frequency of operation that is within an acceptable operating tolerance. The on-chip precision oscillator is used as a time base and then the period of the on-chip oscillator is measured as a function of the time base. The difference between the measured frequency of the on-chip non-precision oscillator and a desired operating frequency of the on-chip non-precision oscillator is then determined. After the difference is determined, the frequency of the on-chip non-precision oscillator is adjusted to minimize the determined difference.

    摘要： Method and apparatus for accessing paged memory with indirect addressing. A a method for changing pages of memory in an indirect addressed memory having a plurality of addressable locations therein is diclosed. An index indicative of the page of the memory being addressed is stored in a memory location. The memory is addressed with a direct address that selects one or more of the addressable locations in the addressed page of memory. An interrupt is received from a resource capable of generating an interrupt, which interrupt has associated therewith a defined one of the pages of memory. In response to generation of the interrupt, the value of the stored index t is changed o an index associated with the defined one of the pages of memory associated with the resource. In response to receiving a signal indicative of the generated interrupt having been serviced by a system that services interrupts, the stored index is changed to a different index.

These functional blocks allow the processing core to interface with the plurality of input/output pins, each of the functional input/output blocks having an associated and predetermined functionality. This functionality comprises the output as a function of the input, the function defined by the functionality. Each of the functional input/output blocks has a requirement for a defined number of the plurality of input/output pins wherein the total of the defined number for all of the plurality of functional input/output blocks exceeds the number of the plurality of input/output pins and wherein the processor core is interfaced with one of the input or output of each of the functional blocks. A reconfigurable interface selectively interfaces between the other of the input or output of the functional blocks and a select one or ones of the plurality of input/output pins, such that the processor core can be interfaced with the select one or ones of the input/output pins. The reconfigurable interface is operable to define how each of the plurality of input/output pins interfaces with the select ones of the plurality of functional blocks and the associated functionality in accordance with configuration information. A non-volatile memory is provided for storing information for use in association with the configuration information, such that the stored information can be altered.

    摘要： A method is disclosed for converting DC power from a first voltage level on an input to a different voltage level on an output for delivery to a load. The method includes switching current in a switching operation from the input to the output through an inductive element and measuring the voltage/current parameters on the input and output. A control algorithm is then utilized to determine control parameters necessary to make a control move to effect the switching operation, the control algorithm utilizing as inputs the measured voltage/current parameters. A digital control system controls the switching operation, which digital control system is operable to be controlled by the control algorithm. Configuration data is received on a serial data bus for configuring the control algorithm. Thereafter, the operation of the control algorithm is modified in response to receiving the configuration information.

    摘要： Digital control circuit for switching power supply with pattern generator. A method is disclosed for converting DC power from a first voltage level on an input to a different voltage level on an output for delivery to a load. Current from the input is switched to the output through an inductive element with a plurality of switches, each of the switches driven by a waveform, all of the waveforms driving the switches referenced with a predetermined relationship to a master clock and all operating on a PWM duty cycle of the master clock. The voltage/current parameters on the input and output are measured and then a control algorithm is utilized to determine a change in the PWM duty cycle necessary to make a control move, the control algorithm utilizing as inputs the measured voltage/current parameters. A pre-stored waveform pattern for each of the waveforms is then modified to reflect the change in the PWM duty cycle required for the control move. After modification, the modified pattern is output to create the waveform and drive the respective switches.
