Patent EP-0472879-A2 (EP)
Inventor: CHALASANI SURESH
IPC: G06F15/167
Filed: 1991-07-16
Abstract: A method and apparatus for routing processor-memory data traffic in a shared-memory multiprocessor computer system employs an interconnection network including two buffered multistage switching networks. Each of these networks can be used to route the data from any processing element to any memory element. Depending on the nature of the processor-memory traffic, two distinct routing schemes are used to distribute the traffic among the two networks. The first method distributes the memory accesses evenly among the two networks and maximizes performance when the memory accesses are uniformly distributed among the memory modules. However, when the traffic is highly non-uniform, a second routing method is used to confine the non-uniform part of the traffic to one network and the remaining part to the other network. The routing method is selected based on the prevailing traffic conditions. A distributed feedback mechanism detects the change in traffic conditions and changes the routing method accordingly. A traffic monitoring circuit within each memory module monitors the traffic into the memory module continuously and senses a change in the traffic condition. The condition is conveyed to the processing elements by means of a status flag associated with each response message from the memory module to processing elements. The processing elements respond to a change in traffic condition by switching to the alternate routing method.

Abstract: In a vehicle suspension controller (15) in which the output of a vehicle body-mounted absolute vertical acceleration sensor (16) is integrated to provide an absolute vertical velocity signal, the sensor output is high-pass filtered to remove DC components and to pass components in the frequency range of 1-2 Hz. The filter comprises a second order digital all-pass filter embodied recursively on a 16-bit, fixed point, digital signal processor (67). A first stage normalized lattice two-pair network reduces to a unity gain stage; and a second stage single multiplier two-pair lattice network minimizes computational time. The 32-bit internal accumulators of the 16-bit digital signal processors (67) are used advantageously to prevent errors due to internal overflow of the recursive variable (e n-1 ).

Abstract: A highlight raster output scanner is disclosed which utilizes an amplitude modulation with its reference level being placed at its white level (32;Fig. 2). Having the reference level at the white level provides the possibility of utilizing two independent power drivers (44,46) to generate modulation pulses (Fig. 2). One power driver (44) generates color pulses (34;Fig.2) (above the white level) and the second power driver (46) generates black pulses (36;Fig. 2) (below the white level). Since an independent power driver (44) is generating the color pulses, the color level (34) can be raised to saturation to prevent the nonuniformity of the intensity of the light beam for color. Also, any intensity variation of the white level (32) can be adjusted by comparing the white level against the reference level. Finally, the black level (36) is kept at ground potential.
