    • A method and apparatus to optimize buffer memory management in a computer system communications resource. The present invention decreases the time for receiving data from and transmitting data to a network by providing for receipt and transmittal of a data packet, prior to the data packet being in a communications resource buffer memory. Consequently, data spends less time in the communications resource buffer memory. This allows a communications resource to handle more data without increasing the size of its buffer memory and to increase the effective data transfer rate. The present invention provides a means for: 1) starting the transmission of data into the network before all data has been transferred to buffer memory in the communications resource, 2) beginning the transfer of data from the buffer memory of the communications resource before the complete data packet has been received and stored in buffer memory, and 3) error checking to insure data integrity.
    • 一种用于优化计算机系统通信资源中的缓冲存储器管理的方法和装置。 本发明通过在数据分组在通信资源缓冲存储器中之前提供数据分组的接收和发送来减少从网络接收数据和向网络发送数据的时间。 因此,数据在通信资源缓冲存储器中花费更少的时间。 这允许通信资源处理更多的数据,而不增加其缓冲存储器的大小并增加有效的数据传输速率。 本发明提供了一种用于:1)在所有数据已经​​被传送到通信资源中的缓冲存储器之前,开始将数据传输到网络中,2)在完成之前开始从通信资源的缓冲存储器传送数据 数据包已被接收并存储在缓冲存储器中,3)错误检查以确保数据完整性。

    • A method is presented that may reduce the number of I/O transactions needed to transfer data between a host device and peripheral device over a parallel port. According to one embodiment, only two I/O transactions are needed to transfer a byte of data as opposed to the eight I/O transactions need in the IEEE 1284-1994 standard. During the two I/O transactions (e.g., transferring data from the host device to the peripheral device), the host device places the data on the data signal lines of the parallel port and toggles a signal on one of the control signal lines. In response, the peripheral device reads the data from the parallel port. Additional bytes can be sent by placing the data onto the port and toggling the signal on the same control signal line. Using this method, a data rate of approximately 4 Mega bits per second may be achieved.
    • 提出了一种可以减少在主机设备和外围设备之间通过并行端口传输数据所需的I / O事务数量的方法。 根据一个实施例,与IEEE 1284-1994标准中需要的八个I / O事务相反,仅需要两个I / O事务来传送数据字节。 在两个I / O事务期间(例如,将数据从主机设备传送到外围设备)中,主机设备将数据放置在并行端口的数据信号线上,并在一个控制信号线上切换信号。 作为响应,外围设备从并行端口读取数据。 可以通过将数据放入端口并在同一控制信号线上切换信号来发送附加字节。 使用该方法,可以实现每秒大约4兆比特的数据速率。
