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.

摘要： Paging scheme for a microcontroller for extending available register space. A method for paging at least a portion of an address space in a processing system is disclosed. A plurality of addressable memory locations are provided arranged in pages. Each of the addressable memory locations in each of the pages occupies at least a portion of the address space of the processing system and has an associated address in the address space of the processing system. A page pointer is stored in a storage location to define the desired page and then an address is generated in the at least a portion of the address space of the processing system. At least one of the addressable memory locations in at least two of the pages with the same address has identical information stored therein. The one of the addressable memory locations associated with both the generated address in the at least a portion of the address space in the processing system and the page pointer is then accessed

摘要： A monolithic digital power supply controller is disclosed for controlling the operation of a switched power supply. The controller is contained within an integrated circuit package enclosing an integrated circuit chip. A plurality of inputs are provided on the package for interfacing with the switched power supply for receiving sensed inputs therefrom. A plurality of outputs provide switch control signals for turning on and off switches in the switched power supply. An integrated digital controller on the chip receives the inputs and generates the outputs, and includes an integrated instruction based processing engine for providing a portion of the digital control of the digital controller. A memory associated with the processing engine stores instructions for the processing engine.
