    摘要: A computer system having a core logic chipset that functions as a bridge between an Accelerated Graphics Port ("AGP") bus device such as a graphics controller, and a host processor and computer system memory wherein a Graphics Address Remapping Table ("GART table") is used by the core logic chipset to remap virtual memory addresses used by the AGP graphics controller into physical memory addresses that reside in the computer system memory. The GART table enables the AGP graphics controller to work in contiguous virtual memory address space, but actually use non-contiguous blocks or pages of physical system memory to store textures, command lists and the like. The GART table is made up of a plurality of entries, each entry comprising an address pointer to a base address of a page of graphics data in the computer system physical memory, and feature flags that may be used to customize the associated page of graphics data. One of the feature flags is used as a link bit for each GART table entry such that when the core logic chipset reads selected ones of the GART table entries stored in the system memory, it stores a first one of the selected ones in its cache memory and determines if the link bit thereof is set. If the link bit of the first one of the selected ones is set then a next one of the selected ones is stored in the cache memory and if the link bit thereof is set then a subsequent one of the selected ones is stored in the cache memory until one of the link bits thereof is determined not to be set.

    摘要: A computer system having a core logic chipset that functions as a bridge between an Accelerated Graphics Port ("AGP") bus device such as a graphics controller, and a host processor and computer system memory wherein a Graphics Address Remapping Table ("GART table") is used by the core logic chipset to remap virtual memory addresses used by the AGP graphics controller into physical memory addresses that reside in the computer system memory. The GART table enables the AGP graphics controller to work in contiguous virtual memory address space, but actually use non-contiguous blocks or pages of physical system memory to store textures, command lists and the like. The GART table is made up of a plurality of entries, each entry comprising an address pointer to a base address of a page of graphics data in memory, and feature flags that may be used to customize the associated page. The core logic chipset may cache a subset of the most recently used GART table entries to increase AGP performance when performing the address translation. A GART cache entry control register is used by an application programming interface, such as a GART miniport driver, to indicate to the core logic chipset that an individual GART table entry in the chipset cache should be invalidated and/or updated. The core logic chipset may then perform the required invalidate and/or update operation on the individual GART table entry without having to flush or otherwise disturb the other still relevant GART table entries stored in the cache.

One of the feature flags is used as a Present Bit for a corresponding memory page. When the feature flag Present Bit is set, the memory page has been reserved in the physical memory for graphics data and an address translation may be carried out. When the feature flag Present Bit is clear, the memory page has not been reserved for graphics data in the physical memory and a determination must then be made whether to perform the translation or generate an error signal to the computer processor.

The GART table enables the AGP graphics controller to work in contiguous virtual memory address space, but actually use non-contiguous blocks or pages of physical system memory to store textures, command lists and the like. Contiguous virtual memory address space must be allocated for the AGP device within the addressable memory space of the computer system, typically 4 gigabytes using 32 bit addressing. The required amount of virtual memory address space for AGP is determined from the AGP device and the information is put into a register of the core logic so that the computer system software may allocate the required amount of memory and assign a base address thereto during computer system startup or POST. An AGP Valid bit is set to indicate whether an AGP device is present or not. If the AGP device is not present, then no virtual memory address space is allocated during the computer system startup.

    摘要: Varying insertion rates of deletable characters that are discarded by a receiver, as a function of transmission rate in spread spectrum clocking systems. Such systems can generate a spread spectrum modulation, based on their knowledge about the rate of transmission. The systems can dynamically adjust the rate/numbers of deletable characters that are inserted in the transmission. Accordingly, the insertion rate can increase (or decrease) when the transmission rate exceeds above (or falls below) a predetermined threshold.

    摘要: A method for scheduling packet data transmissions in a wireless communication system is described wherein a priority function is based on a channel state indicator (CSI), the projected average throughput of the users, and a tuning parameter designed to control the throughput and fairness characteristics of the scheduling algorithm. The method also considers fairness criteria dictated by predetermined Quality of Service (QoS) requirements. The channel state indicator may be a Requested Data Rate (RDR) or Carrier-to-Interference ratio (C/I) information. The base station calculates a priority function for the multiple mobile users. Each priority function is a function of the CSI, the projected average throughput of a given mobile user, the average projected throughput over a set of users, and the tuning parameter.
