摘要： The invention provides a printer with a capability of printing in any one of a plurality of rotations. Component image data is stored in a library. The component image data is subdivided into data sets or quads (30-33). The size of a quad is selected so that it can be readily rotated with simple hardware. As the data sets are written to a buffer (44), they are rotated, and the locations in the buffer at which the different data sets are written depends oil the selected rotation, to provide for data rotation "on the fly" .

摘要： © An interface circuit for connecting a memory controller (208) to either a synchronous bus or an asynchronous bus. The interface circuit comprises switch means (197) for supplying a signal indicative of the type of bus and synchronizing means (198) for synchronizing memory access request signals with a local clock when the interface circuit is coupled to an asynchronous bus.
An interface method of connecting memory circuits to either a synchronous bus or an asynchronous bus. The method comprises the generation of a mode signal indicative of the type of bus, and the synchronization of the memory access request signals with a local clock when the mode signals indicate an asynchronous bus.
