摘要： A system and method is provided for integrating corneal topographic data and ocular wavefront data with primary ametropia measurements to create a soft contact lens design. Corneal topographic data is used to design a better fitting soft contact lens by achieving a contact lens back surface which is uniquely matched to a particular corneal topography, or which is an averaged shape based on the particular corneal topography. In the case of a uniquely matched contact lens back surface, the unique back surface design also corrects for the primary and higher order optical aberrations of the cornea. Additionally, ocular wavefront analysis is used to determine the total optical aberration present in the eye. The total optical aberration, less any corneal optical aberration corrected utilizing the contact lens back surface, is corrected via the contact lens front surface design. The contact lens front surface is further designed to take into account the conventional refractive prescription elements required for a particular eye. As a result, the lens produced exhibits an improved custom fit, optimal refractive error correction and vision.

摘要： A computer system includes an adaptive memory arbiter for prioritizing memory access requests, including a self-adjusting, programmable request-priority ranking system. The memory arbiter adapts during every arbitration cycle, reducing the priority of any request which wins memory arbitration. Thus, a memory request initially holding a low priority ranking may gradually advance in priority until that request wins memory arbitration. Such a scheme prevents lower-priority devices from becoming “memory-starved.” Because some types of memory requests (such as refresh requests and memory reads) inherently require faster memory access than other requests (such as memory writes), the adaptive memory arbiter additionally integrates a nonadjustable priority structure into the adaptive ranking system which guarantees faster service to the most urgent requests. Also, the adaptive memory arbitration scheme introduces a flexible method of adjustable priority-weighting which permits selected devices to transact a programmable number of consecutive memory accesses without those devices losing request priority.
摘要翻译：计算机系统包括用于对存储器访问请求进行优先级的自适应存储器仲裁器，包括自调整可编程请求优先级排序系统。存储器仲裁器在每个仲裁周期内进行调整，从而降低获取内存仲裁的任何请求的优先级。因此，初始保持低优先级排序的存储器请求可以逐渐提前优先，直到该请求赢得存储器仲裁。这样的方案可防止低优先级的设备变得“记忆不足”。因为某些类型的存储器请求（例如刷新请求和存储器读取）固有地需要比其他请求（诸如存储器写入）更快的存储器访问，所以自适应存储器仲裁器另外将不可调整的优先级结构集成到自适应排名系统中，从而保证更快的服务最迫切的要求。此外，自适应存储器仲裁方案引入了可调整优先权重的灵活方法，其允许所选择的设备在没有丢失请求优先级的情况下处理可编程数量的连续存储器访问。

摘要： A computer system includes a CPU and a memory device coupled by a bridge logic unit. CPU to memory write requests (including the data to be written) are temporarily stored in a queue in the bridge logic unit. The bridge logic unit preferably begins a write cycle to the memory device before all of the write data has been stored in the queue and available to the memory device. By beginning the memory cycle as early as possible, the total amount of time required to store all of the write data in the queue and then de-queue the data from the queue is reduced. Consequently, many CPU to memory write transactions are performed more efficiently and generally with less latency than previously possible.

摘要： A computer system includes a CPU, a memory device, two expansion buses, and a bridge logic unit coupling together the CPU, the memory device and the expansion buses. The CPU couples to the bridge logic unit via a CPU bus and the memory device couples to the bridge logic unit via a memory bus. The bridge logic unit generally routes bus cycle requests from one of the four buses to another of the buses while concurrently routing bus cycle requests to another pair of buses. The bridge logic unit preferably includes four interfaces, one each to the CPU, memory device and the two expansion buses. Each pair of interfaces are coupled by at least one queue; write requests are stored (or “posted”) in write queues and read data are stored in read queues. Because each interface can communicate concurrently with all other interfaces via the read and write queues, the possibility exists that a first interface cannot access a second interface because the second interface is busy processing read or write requests from a third interface, thus starving the first interface for access to the second interface. To remedy this starvation problem, the bridge logic unit prevents the third interface from posting additional write requests to its write queue, thereby permitting the first interface access to the second interface. Further, read cycles may be retried from one interface to allow another interface to complete its bus transactions.

摘要： A computer is provided having a bus interface unit coupled between a CPU bus, a PCI bus and/or a graphics bus. The bus interface unit includes controllers linked to the respective buses and further includes a plurality of queues placed within address and data paths linking the various controllers. An interface controller coupled between a peripheral bus (excluding the CPU local bus) determines if an address forwarded from a peripheral device is the first address within a sequence of addresses used to select a set of quad words constituting a cache line. If that address (i.e., target address) is not the first address (i.e., initial address) in that sequence, then the target address is modified so that it becomes the initial address in that sequence. An offset between the target address and the modified address is denoted as a count value. The initial address aligns the reads to a cacheline boundary and stores in successive order the quad words of the cacheline in the queue of the bus interface unit. Quad words arriving in the queue prior to a quad word attributed to the target address are discarded. This ensures the interface controller, and eventually the peripheral device, will read quad words in successive address order, and all subsequently read quad words will also be sent in successive order until the peripheral read transaction is complete.
摘要翻译：提供一种具有耦合在CPU总线，PCI总线和/或图形总线之间的总线接口单元的计算机。总线接口单元包括链接到各个总线的控制器，还包括放置在连接各种控制器的地址和数据路径内的多个队列。耦合在外围总线（不包括CPU本地总线）之间的接口控制器确定从外围设备转发的地址是否是用于选择构成高速缓存行的一组四字的地址序列内的第一地址。如果该地址（即，目标地址）不是该序列中的第一地址（即，初始地址），则修改目标地址，使其成为该序列中的初始地址。目标地址与修改地址之间的偏移量表示为计数值。初始地址将读取对齐到高速缓存行边界，并以连续顺序存储总线接口单元队列中的高速缓存行的四个字。在归因于目标地址的四字之前到达队列的四字被丢弃。这确保接口控制器以及最终的外围设备将以连续的地址顺序读取四个字，并且所有随后读取的四字都将以连续的顺序发送，直到外设读取事务完成。

摘要： An apparatus for monitoring and decoding processor bus cycles and flushing a second level cache upon decoding a special flush acknowledge cycle. The CPU preferably includes an internal cache and a flush input for receiving a signal commanding the CPU to flush its internal cache. After flushing its cache by performing any necessary cycles to write back dirty data to main memory, the CPU performs a special flush acknowledge cycle to inform external devices that the flush procedure has been completed. A cache controller detects the flush acknowledge cycle and provides a flush signal to the second level cache. The cache controller then provides an end of cycle signal to the CPU to indicate that the flush cycle has been acknowledged.

摘要： A memory controller which provides a series of queues between the processor and the PCI bus and the memory system. Memory coherency is maintained in two different ways. Before any read operations are accepted from the PCI bus, both of the posting queues must be empty. A content addressable memory (CAM) is utilized as the PCI to memory queue. When the processor performs a read request, the CAM is checked to determine if one of the pending write operations in the PCI to memory queue is to the same address as the read operation of the processor. If so, the read operation is not executed until the PCI memory queue is cleared of the write. To resolve the problem of aborting a Memory Read Multiple operation, an abort signal from the PCI bus interface is received and as soon thereafter as can be done the read ahead cycle is terminated, even though the read ahead cycle has not fully completed. The memory controller has improved prediction rules based on whether the cycle is coming from the processor or is coming from the PCI bus to allow more efficient precharging when PCI bus cycles are used. The memory controller is highly programmable for multiple speeds and types of processors and several speeds of memory devices. The memory controller includes a plurality of registers that specify number of clock periods for the particular portions of a conventional DRAM cycle which are used to control state machine operations.
摘要翻译：存储器控制器，其在处理器和PCI总线与存储器系统之间提供一系列队列。内存一致性以两种不同的方式保持。在PCI总线接受任何读操作之前，两个发送队列都必须为空。内容可寻址存储器（CAM）被用作PCI到存储器队列。当处理器执行读取请求时，检查CAM以确定PCI到存储器队列中的待处理写入操作之一是否与处理器的读取操作相同。如果是这样，则在PCI存储器队列清除写入之前，不执行读取操作。为了解决中止“内存读取多个”操作的问题，接收到来自PCI总线接口的中断信号，并且尽快完成读取前一周期，即使前面的读取周期尚未完全完成。存储器控制器基于该周期是来自处理器还是来自PCI总线来改进预测规则，以在使用PCI总线周期时允许更有效的预充电。存储器控制器是高度可编程的，适用于多种速度和类型的处理器和几种存储器件的速度。存储器控制器包括多个寄存器，其指定用于控制状态机操作的常规DRAM周期的特定部分的时钟周期数。
