  • Patent number: 6678774
    Abstract: An arbiter apparatus for selecting an agent to use a shared resource such as memory. A normal round robin list is utilized in the selection process during boot operation. During the initialization process, a dynamic list is generated in accordance with system requirements. The dynamic list selection process may take any of several forms. In a first mode, it may select only priority listed agents, any one of which may be repeated during a given cycle of selection. In a second mode, it may select a designated buddy agent when the selected priority agent is idle. In either mode, and in accordance with a set of priority selection rules, one or more lowest priority default agents may be given access when the designated higher priority agents for a given list entry slot are idle.

  • Patent number: 5487051
    Abstract: An electronic data storage memory performs logic operations on the data values existing in its storage cells to eliminate the number of necessary memory accesses during bitblts. The time in which a bitblt can be completed in an image processing system is prolonged because of the number of memory cycles performed during a "raster operation". Thus, to reduce the number of necessary memory cycles, simple logic operations are performed in image processor memory so that a raster operation may take place without having to read, for example, the destination operand from memory. Since a bitblt performs a raster operation on each pixel in the bitblt block, the reduction in memory access time is proportional to the size of the bitblt block.

  • Patent number: 5347631
    Abstract: The number of required clock periods in a bit aligned block transfer operation may be reduced by analyzing the logical relationship between source, destination and pattern operands prior to fetching these operands from memory. If the result of the raster operation can be determined without actually using the value of any of the operands, the result is provided without reading memory values. When the raster operation will have no effect on the existing destination operand, the write operation is also canceled.

  • Patent number: 4849924
    Abstract: An apparatus for counting occurrences of a plurality of events characterized by unique event numbers includes a random access memory for storing event count numbers at addresses corresponding to the event numbers. The memory is addressed by an event number as the associated event occurs, and the event count number stored at such address is read and latched to an input of an adder. The adder increments the latched event count number and the incremented event count number is then written back into the memory at the current event number address. A buffer is provided to store the current event number whenever the adder overflows as a result of a count. Several such event numbers may be stored in the buffer for subsequent retrieval by an external controller thereby permitting the controller to determine when an event has been counted a fixed number of times and to increment its own internally stored count at a slower rate than the rate at which data is applied to the prescaler.
