摘要： A disk drive array including a controller which provides scatter/scatter (bi-directional scatter/gather) operations between noncontiguous host memory address locations and noncontiguous disk address locations. The host provides a single request to launch a scatter/scatter transfer. The single data request includes a pointer to a list of transfer counts and addresses, the length of the list, and the starting logical address on the disk transfer. Skipped blocks in a scatter/scatter request are specified by data address value of -1, and a no-operation (no-op) request is enqueued for each skipped block. Thus, during reads the controller extends the scattered read from the disk into a single large read of contiguous sectors and suppresses the unwanted data by inserting "no-operation" commands in place of the read commands during the transfer to the host.

摘要： An improved read ahead strategy that improves the performance of a disk array subsystem. The disk controller keeps track of the last n reads to the array. If a new read request is received that is adjacent to any of the last n reads, the controller performs a look ahead read because a sequential read may be in progress. The parameter n is preferably set comparable to or greater than the number of maximum independent activites being performed by the computer system. Therefore, in a multithread system, the controller performs a readahead if any one thread is doing a sequential read.
摘要翻译：改进的预读策略，提高磁盘阵列子系统的性能。磁盘控制器跟踪阵列的最后n次读取。如果接收到与最后n次读取中的任何一个相邻的新的读取请求，则控制器执行预览读取，因为顺序读取可能正在进行中。优选地将参数n设置为等于或大于由计算机系统执行的最大独立运动的数量。因此，在多线程系统中，如果任何一个线程进行顺序读取，则控制器执行readahead。

摘要： A caching disk controller is provided which includes a bus bridge that forms an interface between a memory of the disk controller and a host computer. The caching disk controller further includes a SCSI processor for controlling the transfer of data from a SCSI disk drive to the memory via a local bus. A zero latency DMA controller embodied within the bus bridge snoops the local bus as data is being transferred from the SCSI disk drive to the memory, and thereby allows the data to be sequentially latched within a data FIFO of the bus bridge concurrently with its transfer into the memory. As a result, the requested data may be advantageously provided from the bus bridge to the host computer with reduced delay, while the data continues to be stored within the memory to accommodate high hit rates during subsequent transfers.

摘要： A device for interfacing an expansion bus with an option card and an associated method for initializing a computer system having the option card installed on the expansion bus thereof. The interface device includes a dual ported RAM having a first port coupled to the expansion bus and a second port coupled to the option card, a processor coupled to the second port of the dual ported RAM and a non-volatile memory coupled to the processor and to the second port of the dual ported RAM. At power up, the processor transfers an expansion BIOS and pattern stored in the non-volatile memory to first and second portions, respectively, of the memory space of the dual ported RAM. The computer system scans the second portion of the dual ported RAM for the pattern, executes a first initialization sequence contained in the expansion BIOS upon detecting the pattern and then executes a second initialization sequence contained in a BIOS of the computer system. Data acquired during the execution of the initialization sequence is stored in a third portion of the memory space. Updates to the expansion BIOS are transferred to a fourth portion of the memory space where the processor transfers the updates to the non-volatile memory. The processor also controls bi-directional exchanges of data and control signals between the expansion bus and the option card via the fourth portion of the memory space.

摘要： A digital computer system includes an interface for routing data which permits the transfer of data between mismatched devices. The computer system comprises a processor, memory and an interconnecting data bus, all configured to handle data units of a first data width. Also connected to the data bus is at least one I/O device configured to handle data units of a second data width. By adjusting the width of the data being transferred to match the width of the receiving device or bus, data may be transferred between devices of differing width. To adjust the width, control means are provided which modify the route along which data bytes are transferred based upon the width of the transferring and receiving devices and the direction of transfer are provided.

摘要： A method and apparatus which provides bi-directional communication between a video monitor and a computer system unit. This enables the video monitor to inform the system unit of its capabilities without direct user involvement and also enables the system unit to directly control or adjust all the functions of the video monitor. In the preferred embodiment, bi-directional communication between the video monitor and the system unit is provided utilizing a mouse port in the keyboard controller. Multiplexors are coupled between the mouse port and each of the mouse and video monitor to select between data paths and selectively allow communication between the system unit and the video monitor. Monitor control software is included in the system unit which can be used to control or adjust the output of the video monitor. When a user desires to adjust the output of the video monitor, the monitor control software directs the multiplexors to provide a communication path between the system unit and the video monitor, and the system unit relates the control information input from the user to the video monitor, which adjusts its visual output accordingly. Also, at each power-on of the computer system, the data path between the keyboard controller and video monitor is selected to enable the video monitor to provide capability information to the system unit.
