    摘要: A computer system providing multiple processors or masters an architecture for highly concurrent processing and data throughput. A multiple channel memory architecture provides concurrent access to memory. Arbitration and snoop logic controls access to each memory channel and maintains cache coherency. A host CPU, multimedia processor, pipes processor and display controller may independently and concurrently access memory. The pipes processor provides a decoupled input/output processor for universal serial bus and firewire serial buses to free up the host CPU.

    摘要: A method and apparatus of allocating memory space in a main memory of a computer system to a unified memory architecture device. The main memory is associated with a physical address space. A required linear address range is determined for the video card, and the linear address range is mapped to scattered portions in the physical address space. A page table is created containing page frame numbers corresponding to page frames in the main memory, the page frames being allocated to the device. The page frames are non-contiguous blocks of the main memory. The device is associated with a linear address space. The frame numbers are loaded into a translation look-aside buffer (TLB) for converting a linear address in the linear address space to a physical address in the physical address space.

    摘要: A computer system which includes a DMA controller on the local I/O unit which can be programmed by either the host processor or the local processor. Semaphore flags and lock bits are provided to allow determination of control of the local DMA controller and for passing information. Additionally, data alignment and padding circuitry is provided. The circuitry is informed of the logical data arrangement desired or utilized by the host processor or other devices and knows the data arrangement of the local processor. The circuitry properly obtains and realigns the data based on the transfer direction and data arrangement. The circuitry further properly zero pads the data when realignment is such that padding is necessary.

    摘要: A method and apparatus of assuring uniqueness of identification numbers of bus devices connected to a bus. Each bus device has a current identification number. At each of the bus devices, an identification number is received on a bus and the bus is contended for based on the received identification number. If more than one bus device is detected contending for the bus, the current identification number of one of the bus devices is changed. Each of the bus devices compares the received identification number to the current identification number of the bus device. A bus device provides a match indication, including driving a signal, if the comparison produces a match. Each bus device includes a collision detector for detecting if more than one bus device is driving the signal.
