Abstract: There is provided a printer control apparatus which can be applied to an image forming apparatus in which a plurality of types of readers and a plurality of types of printers can be connected to a single controller, and which enable efficient transfer of image data from the reader to the printer via an image memory of the controller. The controller receives image data from a reader and temporarily stores the same in an image memory, and transmits the stored image data to a printer. The controller acquires a reader processing speed from the reader and a printer processing speed from the printer, and determines, while the image data is being written to the image memory, timing for transmitting the image data written in the memory to the printer according to a difference between the reader processing speed and the printer processing speed and a sub-scan size of the image data. The controller causes the reader to start reading an original, and transmits the written image data from the image memory to the printer in the determined timing.

Abstract: The present invention discloses methods by which client computers working in a host operating environment can use from external data sources, which methods do not require nonvolatile storage of the data as native data to the host operating environment. The methods operate transparently to a user of a client computer using the data through the host operating environment, and allow the data to be used as a first class participant in the host operating environment. Changes to the data can be saved nonvolitilely in the external data sources.

Abstract: A host signal processing accelerator and method of using the same is provided in which certain signal processing tasks which are computing intensive but are contained in short lengths of code are downloaded from the host processor to the accelerator for processing. Signal processing tasks such as FIR (finite impulse response), IIR (infinite impulse response), and FFT/IFFT (fast Fourier transform/inverse fast Fourier transform) are sent from the host processor in machine code form to a double-buffered command memory for downloading onto the system bus. The task is loaded into a command buffer located on the accelerator, and is then passed to the accelerator's signal processor for execution. The results are sent to a status buffer on the host processor.

Abstract: An electronic method and apparatus for a communication system coupling a target device and a plurality of accessing devices to a bus. One of the plurality of accessing devices requests access to the target device. The target device then acquires GUID data from the requesting device. The acquired GUID data is compared to preliminary GUID data stored in the target device. When the acquired GUID data coincides with the preliminary GUID data, the target device releases access allowing function data to the accessing device. On the other hand, when the acquired GUID data does not coincide with the preliminary GUID data, the target electronic apparatus releases access prohibiting function data to the accessing device.

Abstract: A method and circuit for controlling a FIFO buffer such that the buffer can accommodate more than one data block simultaneously without overlapping data between adjacent data blocks. The FIFO buffer has a read-pointer address register and a write-pointer address register and a bank of write-capture registers including at least a first pair and a second. The first pair of registers captures and saves the write-pointer addresses associated with the beginning and ending of a first data block written to the FIFO buffer register while the second pair of registers captures and saves the write-pointer addresses associated with the beginning and ending of a second data block written to the FIFO buffer. The first pair and second pair alternate in capturing and saving beginning and ending addresses of a plurality of data block written to the FIFO buffer. In reading data from the FIFO buffer, the read pointer address register is loaded with the previously saved write-pointer address associated with the beginning of each data block that is subsequently read. Since both the beginning and ending write-pointer addresses associated with each data block are captured and saved, the system reading from the FIFO buffer delineates between adjacent data blocks, thereby eliminating data overlap or FIFO interruption.
