    • A printing machine, of the type in which image data, addresses and control data can be substantially concurrently transferred across multiple multipurpose buses, is provided. The printing machine comprises a first multipurpose bus (320) adapted to transfer, substantially concurrently, a first set of the image data, addresses and control data and a second multipurpose bus (324) adapted to transfer substantially concurrently, a second set of the image data, addresses and control data. A module (302) for processing the first and second sets of data communicates with the first and second multipurpose buses while a first discrete input/output module (307, for example) communicates with the first bus. Both the first processing module and the first discrete input/output module are adapted to transfer the first set of data between one another. A second discrete input/output module (306, for example) communicates with the second multipurpose bus and a third discrete input/output module (310, for example) communicates with the second multipurpose bus. Both the second and third discrete input/output modules are adapted to transfer the second set of data between one another. Preferably, the first set of data can be transferred between the processing module and the first discrete input/output module substantially concurrent with the second set of data being transferred between the second discrete input/output module and the third discrete input/output module.
    • 提供了一种能够将图像数据,地址和控制数据基本上同时传送到多个多用途总线上的打印机。 印刷机包括适于基本同时地传送第一组图像数据,地址和控制数据的第一多用途总线(320)和适于基本同时传送第二组图像的第二多用途总线(324) 数据,地址和控制数据。 用于处理第一和第二组数据的模块(302)与第一和第二多用途总线通信,而第一离散输入/输出模块(例如307)与第一总线通信。 第一处理模块和第一离散输入/输出模块都适于在彼此之间传送第一组数据。 第二分立输入/输出模块(例如306)与第二多用途总线通信,并且第三分立输入/输出模块(例如310)与第二多功能总线通信。 第二和第三离散输入/输出模块都适于在彼此之间传送第二组数据。 优选地,第一组数据可以在处理模块和第一离散输入/输出模块之间传输,基本上与在第二离散输入/输出模块和第三离散输入/输出模块之间传送的第二组数据同时进行。
