摘要： A packet-based communication system is described for linking a peripheral unit (PU) to the outside world via a communications link. The system includes a modular interface unit (MIU) which has a memory shared by processors in both the PU and MIU. The system employs control packets, read packets and write packets and performs a method for allocating the shared memory that optimizes memory utilization. The system determines a ratio of read to write packets required in the operation of the PU, and it ignores that ratio if the communications link will not transmit write packets. If the communication link will transmit write packets, it allocates read and write packet space within the shared memory in accordance with the ratio. The system also includes apparatus for enabling MIU configuration via user/keyboard inputs through the PU with the MIU providing the question and answer messages. This feature allows the PU to adapt to many different communication links, simply by replacement and user configuration of the MIU. The system further includes apparatus for rapidly handling network protocol headers. Those headers are stored along with the data packets and when the packet is accessed by the PU from shared memory, pointers are employed to enable access of only the data portions of such packets while ignoring the network protocol header portions.

摘要： An imaging device and method enable the freeing of memory during a punt (print overrun) avoidance operation and during a duplexing operation for enhanced page throughput. Specifically, if a first race condition threshold is met, being indicative of an estimated need to pre-rasterize a band from a page of image data for punt avoidance, and if after pre-rasterization it is determined pre-rasterization is not actually needed for punt avoidance, then the pre-rasterized band is evaluated relative to its display list for memory savings purposes for improved page throughput performance. Similarly, if a duplex condition threshold is met, being indicative of a band being part of a first side of a duplex page being processed and of an estimated need to save memory for processing of the second side of the duplex page, then the band is pre-rasterized and evaluated relative to its display list for memory savings purposes for improved duplex page throughput performance. If neither the race condition threshold nor duplex condition threshold is met, but an increased general memory savings condition threshold is met for the band, then the band is pre-rasterized for memory savings purposes.

摘要： Apparatus for improved translation of an interleaved binary coded signal heavily masked by noise comprising a plurality of delay line type matched binary code filters for receiving the interleaved signal, preferably of the surface acoustic wave type. Each filter is matched to one of the binary codes from which the interleaved signal is formed. The output signal of each matched filter is split and passed through a delay means and the output of each delay means is summed with the output of each matched filter. The resulting signals can be further processed by adding or multiplying.

摘要： A memory management system usable with a client is provided. The memory defines a memory space including at least one memory buffer, and the memory buffer is defined by a set of attributes including base address and size. The memory includes a fixed-simple memory allocation, having a link, and one of a relocatable simple memory allocation coupled with the link, a head of a complex memory allocation comprising multiple simple memory allocations, or a null simple memory allocation. A memory manager is coupled with the memory and is configured to manage specific instances of memory allocation usable by a client. A memory management interface is coupled with the memory manager and is configurable to enable a client to specify a request for a relocatable memory object. Processing circuitry is coupled with the memory and the memory management interface and is operative to detect a low memory condition. The memory manager is operative to relocate the memory object from one physical location in memory to another physical location in memory to generate a sufficiently large contiguous free memory block for the client so as to overcome the low memory condition. A method is also provided.

摘要： A system and method produce a combined page having all of the composition of a first page plus all of the composition of a second page. Each band of the first page is pre-rasterized then saved to solitary band stores. Next each band of the second page is pre-rasterized and combined with the corresponding solitary band store to produce combined band stores. The combined band stores are then joined to produce the combined page. The combined band stores are joined by printing each combined band store in sequential location on the same page.

摘要： A method of operating a digital printer for producing a printed image on a print medium is described. The method is intended for use with a printer which includes at least one memory for holding an overlay pattern bit map which defines an overlay pattern at least portions of which are utilized in printing the printed image onto the print medium, and an image processor for processing 3image data used to produce the printed image. The method includes defining at least one fill area to be printed with at least a portion of the overlay pattern; reading at least a portion of the overlay pattern bit map from said memory; providing at least one boundary point which in part defines a fill area subset which serves to fill a portion of the fill area and define a portion of the printed image appearing therewithin; applying at least a portion of the overlay pattern bit map read from memory to the fill area subset; writing the fill area subset to an output buffer which stores data defining at least a portion of the printed image; and servicing the print mechanism at variable or constant paper slew rate. According to a preferred embodiment, a 3-parameter model is used to determine the incremental image processing cost of pattern processing.

摘要： An imaging device and method provide memory management tasks on data of a page being composed in response to feedback generated by memory management tasks that are performed on pages in the page pipe that are waiting to be imaged. The feedback is throttled relative to memory management tasks that occur in the pipe. Advantageously, the memory management tasks are performed on the page being composed without waiting for an already composed page to finish imaging. Accordingly, page throughput of a multi-page print job is improved. The memory management tasks include compressing, relocating, and/or compressing and relocating data. Page data on which the memory management tasks are performed include raster patches, fonts, patterns, video bands, monster bands and vector bands. Atomic operations and/or a critical section locking mechanism provide collision avoidance as between the memory management tasks performed on data in the pipe and a video imaging task.
