Filed: 1989-12-05
Abstract: A modularly expandable digital single-stage ATM (Asynchronous Transfer Mode) switching network for high-speed packet-switched information transfer, comprising a preprocessing module (VVM), in which arrangement preprocessing is only carried out with respect to the matrix column but not with respect to the matrix output and the number of expansion inputs and the number of first outputs of the preprocessing module is 1/L, namely N, of that of the expansion module, this module containing a single FIFO store (SP) which can simultaneously enter 2N packets and simultaneously read out N packets and in which arrangement, to avoid so-called overtaking by packets, the order in time of packets in each case arriving on one of the N first-input lines of a preprocessing module (VVM) is replaced case by case by a spatial order on the N first-output lines of the preprocessing module (VVM). An overhead information filter (KF) only processes a part of the overhead information of the data packets for switching the packets to the relevant switching module column. In addition, a further preprocessing module (VVM) and a final processing module (EVM), which carries out final switching to the matrix output, are provided per matrix column, in which arrangement the first outputs of these preprocessing modules (VVM) are connected to the relevant inputs of the final processing modules (EVM). The final processing modules (EVM) do not have any expansion inputs or expansion outputs. The overhead information filter (KF) of the final processing module (EVM) processes a different part of the overhead information for the final switching to a matrix output.

Patent EP-0382358-A3 (EP)
Title: Full address and odd boundary direct memory access controller
IPC: G06F12/08
Filed: 1990-01-19
Abstract: The computer system disclosed includes a direct 
memory access (DMA) controller which can provide a 32 bit 
memory address and yet can also provide 24 bit memory 
address operation to remain compatible with previous 
systems. The DMA controller also monitors system 
operation and if only 24 bit address operations are 
occurring under the control of an external bus master or 
the DMA controller, the DMA controller drives the top 
memory address byte provided to a cache memory controller 
to help insure cache coherency. Additionally, the DMA 
controller can provide optimal time transfers for word 
width transfer between an odd starting memory address and 
an even starting input/output port.

Patent EP-0400839-A3 (EP)
Title: Microcomputer system employing adress offset mechanism to increase the supported cache memory capacity
IPC: G06F12/08
Filed: 1990-05-16
Abstract: The capacity of cache memory supported by a cache controller can be 
increased by offsetting the relationship between CPU address output 
terminals and address input terminals of the cache controller and 
correspondingly doubling the cache line size. In some cases, 
additional logic generates a hidden memory cycle so as to fetch from 
memory that number of bytes equal to the new line size regardless of 
the width of the data bus. The hidden memory cycle is initiated by a 
read miss and further logic generates a memory address which is not 
generated by the CPU. The hidden memory cycle is maintained 
transparent to the CPU and cache controller by inhibiting the change in 
a READY signal until completion of both the normal memory cycle and the 
hidden memory cycle.

Title: Image generator.
Inventor: BAKER STEPHEN JOHN
IPC: G06T15/00
Filed: 1989-12-05
Abstract: An apparatus for generating an image to be displayed on a display screen from data defining a model including a plurality of opaque and translucent features. The image is intended to represent a view of the model from a predetermined eyepoint and is made up from an array of screen space pixels to be displayed by a raster scanning process. Each pixel is of uniform colour and intensity, and the pixels together define an image area. The image area is divided into an array of sub-areas each of which covers at least one pixel. For each feature in the model that is potentially visible from the eyepoint, a test is conducted to determine which of the sub-areas is at least partially covered by that feature. A list of feature identifiers is produced in respect of each sub-area, the list for any one sub-area identifying features which at least partially cover that sub-area. The position in screen space of at least one sampling point within each sub-area is determined. For each sub-area in turn, and for each sampling point a test is conducted to determine which of the features in that sub-area's list cover that sampling point. For each feature which covers a sampling point, a function of the distance from the eyepoint to that feature at the sampling point is determined. Feature describing data is stored for each sampling point within a sub-area, the stored data being indicative of at least the distance of the opaque feature which covers the sampling point and is nearest to the eyepoint and the distance and translucency of at least one nearer translucent feature which covers the sampling point. An output is produced for each sampling point within a sub-area, the sampling point output corresponding to the combined effects of the features identified by the stored data. An output for each pixel within a sub-area is produced, the pixel output corresponding to the combined effects of the sampling point outputs for all sampling points which contribute to that pixel, and the pixel outputs are displayed. <IMAGE>
