| 5535373 | Protocol-to-protocol translator for interfacing disparate serial network nodes to a common parallel switching network A generic network device includes a serial line switching apparatus for performing either parallel or serial communications amongst multiple nodes over switching networks. An aspect includes the adaptation of standard and proprietary serial interfaces usi... | 07/09/1996 |
| 5495474 | Switch-based microchannel planar apparatus A modularly expandable switch-based planar apparatus for insertable multiple bus-based processor cards and/or expansion cards and interconnecting the cards via a multi-stage switch network which resides on the planar apparatus. The cards require no modifi... | 02/27/1996 |
| 5365228 | SYNC-NET- a barrier synchronization apparatus for multi-stage networks A SYNC-NET apparatus synchronizes processor nodes of a parallel system over a multi-stage communication network that normally transmits data between nodes as point-to-point communications, broadcast, multi-cast, or multi-sender transfers. The apparatus pe... | 11/15/1994 |
| 5345229 | Adaptive switching apparatus for multi-stage networks Disclosed is a method and apparatus for improving the performance and connection establishing capability of multi-stage switching networks by providing additional intelligent features in the individual switching apparatus devices at each stage of the netw... | 09/06/1994 |
| 5337395 | SPIN: a sequential pipeline neurocomputer A neural network architecture consisting of input weight multiplications, product summation, neural state calculations, and complete connectivity among the neuron processing elements. Neural networks are modelled using a sequential pipelined neurocomputer... | 08/09/1994 |
| 5313613 | Execution of storage-immediate and storage-storage instructions within cache buffer storage A cache storage system having hardware for in-cache execution of storage-storage and storage-immediate instructions thereby obviating the need for data to be moved from the cache to a separate execution unit and back to cache.... | 05/17/1994 |
| 5250943 | GVT-NET--A Global Virtual Time Calculation Apparatus for Multi-Stage Networks A GVT-NET apparatus for all processor nodes of a parallel system for repetitive calculation of the latest global virtual time (GVT) value quickly and accurately over the communication multi-stage network (NET) that normally transmits data between nodes as... | 10/05/1993 |
| 5243688 | Virtual neurocomputer architectures for neural networks The architectures for a scalable neural processor (SNAP) and a Triangular Scalable Neural Array Processor (T-SNAP) are expanded to handle network simulations where the number of neurons to be modeled exceeds the number of physical neurons implemented. Thi... | 09/07/1993 |
