摘要： A computer system automatically senses characteristics of diverse peripheral devices connected to a common communications port, and automatically maximizes the communications speed with the devices. Coupled in daisy chain fashion to the communications port, all peripheral devices receive every signal issued from the controller port, each device responding only to signals addressed to that device or signals addressed to a universal address. The controller first receives an identifier from peripheral devices attached to the controller port. The controller then interprets the received identifiers to determine a maximum communications speed for each device. Next, the controller and the attached peripheral devices are configured to communicate at the maximum communications speed of the slowest device. This guarantees that all messages sent by the controller are compatible with all peripheral devices. Devices subsequently coupled to the communications port are considered by the controller, and the port and other devices are reconfigured as necessary to ensure the fastest possible communications speed.

摘要： A controller and a properly equipped peripheral device of a computer system easily exchange messages having a compressed data format. Both the controller and the peripheral device are configured to communicate using a predefined basic command set employing a predefined communications format. The controller first verifies that the peripheral device supports a second predefined communications format in addition to the first predefined communications format. Compared to the first format, the second format utilizes messages with greater compression, i.e., an optimized bit stream ("OBS"). The controller next sends the peripheral device a number of commands, including a command of the basic command set accompanied by an OBS enable code. In the case of a write operation, the controller also sends the peripheral device an encoded dataset having the second predefined communications format and representing an underlying unencoded dataset. Although the basic command alone would alert the peripheral device to the transmission of uncompressed data, the presence of the OBS enable code signals a compressed dataset. The peripheral device receives the encoded dataset and, resulting from the received OBS enable code and the command of the basic command set, processes the encoded dataset to obtain the unencoded dataset. In the case of a read operation, the controller receives an encoded dataset, in the second predefined format, from the peripheral device.
摘要翻译：计算机系统的控制器和适当配备的外围设备容易地交换具有压缩数据格式的消息。控制器和外围设备都被配置为使用预定义的通信格式的预定义的基本命令集进行通信。除了第一预定通信格式之外，控制器首先验证外围设备支持第二预定义的通信格式。与第一格式相比，第二格式利用较大压缩的消息，即优化的比特流（“OBS”）。控制器接下来向外围设备发送许多命令，包括伴随着OBS使能码的基本命令集的命令。在写入操作的情况下，控制器还向外围设备发送具有第二预定通信格式的编码数据集并且表示底层未编码的数据集。尽管基本命令本身将提醒外围设备传输未压缩数据，但OBS启用代码的存在可以表示压缩的数据集。外围设备接收编码的数据集，并且由接收的OBS使能码和基本命令集的命令产生，处理编码的数据集以获得未编码的数据集。在读取操作的情况下，控制器从外围设备接收第二预定格式的编码数据集。
