摘要： An apparatus for sharing an interrupt between a controller for a parallel storage device interface and a controller for a serial storage device interface includes interrupt conditioning circuitry that masks an interrupt signal coming from the parallel storage device interface if no storage device is coupled to the parallel storage device interface. The masking of the parallel storage device interface interrupt of no storage device is coupled to the parallel storage device interface allows the controller for the serial storage device interface to share the interrupt traditionally assigned to the parallel storage device interface.

摘要： A first set of instructions and incoming data are provided to a first processing unit of a data driven processor, to operate upon the incoming data. The first processing unit, in response to recognizing that the first set of instructions will require either reading from or writing to external memory, sets up a logical channel between a second processing unit of the processor and the external memory, to transfer additional data between the external memory and the second processing unit. This capability may be implemented by the addition of a control port, separate from data ports, to the first processing unit, where the control port allows the first processing unit to write addressing information and mode information (including the location of the additional data) for reading or writing the additional data via a memory access unit data channel of the processor.

摘要： A memory subsystem that includes a dynamic random-access memory (DRAM) having cells organized as an array of rows and columns, the cells being individually accessed by specifying a row address and a column address. An additional cell that stores a charge level is associated with each row of the DRAM. The charge level is characteristic of the charge level of the associated DRAM row, and is refreshed by a secondary or primary refresh cycle to the associated DRAM row. A threshold detector outputs a refresh signal when the charge of the additional cell drops below a predetermined threshold. Circuitry responsive to the refresh signal collects the row address of the additional cell and sends it to logic that generates a primary refresh cycle to the associated row address of the DRAM.

摘要： A method and apparatus for translating a first address in a first address space, such as a processor address space, to a second address in a second address space, such as system address space, and for accessing a service routine in response to a page fault, are described. In one embodiment, the apparatus for translating comprises a processor; a page table having a translation mask register, a comparison value register, and a replacement value register; and a comparator coupled to the comparison value register and to the replacement value register. A programmable mask within the translation mask register is employed to partition a virtual address. A first subaddress comprises a subset of the bits of the first address and a second subaddress comprises remaining bits of the first address. The first subaddress is masked with a programmable mask value in the translation mask register and is compared by the comparator with successive values in the comparison value register until a match comparison value is found. If a match comparison value is found, a programmable replacement value in the replacement value register corresponding to the match comparison value is concatenated with the second subaddress to provide the second address. If a match comparison value is not found, a fault interrupt is generated to interrupt the translation and the processor accesses a service routine in accordance with the fault interrupt.

摘要： An apparatus for processing visual data includes a first video random access memory (VRAM) for storing a first bit plane of visual data in a first format. A graphics controller is coupled to the first VRAM by a data bus and a storage bus. The apparatus is capable of receiving at least a second VRAM for storing at least a second bit plane of visual data in at least a second format different from the first format. The received VRAMs are coupled to the graphics controller by data and storage busses. The visual data stored on the VRAMs are merged into a pixel stream which is then converted to analog form by a digital to analog converter. Data transfer addresses are generated for each of the VRAMs simultaneously, sequentially or in overlapping timed relationship.

摘要： A request arbitration device is provided for prioritizing requests in a data processing system. A series of requests may arrive at the arbitration device at differing arrival times. The requests are accumulated to form a set of requests which is applied to a priority decode without any information on their relative arrival times. The priority device applies a fixed predetermined priority scheme to these requests. Simultaneously with the prioritizing of the first set of requests by the priority decode, a second set of requests may arrive at different arrival times. The requests of this second set of requests are likewise accumulated by the arbitration logic of a present invention. When arbitration of the first set of requests is complete, the second set of requests is then applied to the priority decode, again without any information with respect to their relative arrival times. The second set of requests is prioritized according to the same fixed predetermined priority scheme as the first set.
