  • Patent number: 5963745
    Abstract: A parallel array processor for massively parallel applications is formed with low power CMOS with DRAM processing while incorporating processing elements on a single chip. Eight processor memory elements on a single chip have their own associated processing element, significant memory, and I/O and are interconnected with a hypercube based, but modified, topology. These nodes are then interconnected, either by a hypercube, modified hypercube, or ring, or ring within ring network topology. The architecture uses all the pins for networking. Each chip has eight 16 bit processors, and eight respective 32K memories. I/O has three internal ports and one external port shared by the plural processors on the chip. Significant software flexibility is provided to enable quick implementation of existing programs written in common languages. The scalable chip has internal and external connections for broadcast and asynchronous SIMD, MIMD and SIMIMD (SIMD/MIMD) with dynamic switching of modes.

  • Patent number: 5963746

Eight processors on a single chip have their own associated processing element, significant memory, and I/O and are interconnected with a hypercube based, but modified, topology. These nodes are then interconnected, either by a hypercube, modified hypercube, or ring, or ring within ring network topology. Conventional microprocessor MMPs consume pins and time going to memory. The new architecture merges processor and memory with multiple PMEs (eight 16 bit processors with 32K and I/O) in DRAM and has no memory access delays and uses all the pins for networking. The chip can be a single node of a fine-grained parallel processor. Each chip will have eight 16 bit processors, each processor providing 5 MIPs performance. I/O has three internal ports and one external port shared by the plural processors on the chip.

  • Patent number: 5842031
    Abstract: A computer system having a plurality of processors and memory including a plurality of scalable nodes having multiple like processor memory elements. Each of the processor memory elements has a plurality of communication paths for communication within a node to other like processor memory elements within the node. Each of the processor memory elements also has a communication path for communication external to the node to another like scalable node of the computer system.

  • Patent number: 5794059
    Abstract: A parallel array processor for massively parallel applications is formed with low power CMOS with DRAWM processing while incorporating processing elements on a single chip, with nodes connected in an n-dimensional modified non-binary hypercube. In a 4-dimensional modified non-binary hypercube embodiment, each node includes either processor memory elements on a single chip, each processor memory element having its own associated processing element, significant memory, and I/O, with each processor memory element supporting an external port. Pairs of ports are associated with each dimension, labeled X, Y, W, and Z. Eight nodes are connected in the X dimension to form a ring. Corresponding nodes from eight such rings are connected into rings in the Y dimension to form an 8.times.8 array of nodes, referred to as a cluster. Corresponding nodes of eight clusters are connected into ring (64 rings) in the Z dimension, forming an 8.times.8.times.8 array of nodes referred to as a "cluster ring".
