G06F 1208

US Classification:

711153

Abstract:

A multiprocessor digital data processing system comprises a plurality of processing cells arranged in a hierarchy of rings.

Frederick D. Weber - Concord MA

Assignee:

Kendall Square Research Corporation - Waltham MA

International Classification:

G06F 1300
G06F 1516

US Classification:

395325

Abstract:

A digital data processing apparatus includes a shift-register bus that transfers packets of digital information. The bus has a plurality of digital storage and transfer stages connected in series in a ring configuration. A plurality of processing cells, each including at least a memory element, are connected in a ring configuration through the bus, with each cell being in communication with an associated subset of stages of the bus. At least one processing cell includes a cell interconnect that performs at least one of modifying, extracting, replicating and transferring a packet based on an association, if any, between a datum identified in that packet and one or more data stored in said associated memory element. The cell interconnect responds to applied digital clock cycle signals for simultaneously transferring at least a selected packet through successive stages of the bus at a rate responsive to the digital clock cycle rate, while performing the modifying, extracting, replicating and transferring operation.

International Classification:

G06F 900

US Classification:

395591

Abstract:

Digital multiprocessor methods and apparatus comprise a plurality of processors, including a first processor for normally processing an instruction stream including instructions from a first instruction source. At least one of the processors can transmit inserted-instructions to the first processor. Inserted-instructions are executed by the first processor in the same manner as, and without affecting the sequence of, instructions from the first instruction source. The first instruction source can be a memory element, including an instruction cache element for storing digital values representative of instructions and program steps, or an execution unit (CEU) which asserts signals to the instruction cache element to cause instructions to be transmitted to the CEU. The processors include input/output (I/O) processors having direct memory access (DMA) insert elements, which respond to a peripheral device to generate DMA inserted-instructions. These DMA inserted-instructions are executable by the first processing element in the same manner as, and without affecting processing sequence of, the instructions from the first instruction source.

International Classification:

G06F 100

US Classification:

395400

Abstract:

A digital data processing apparatus has plural processing cells, each with a memory element that stores data page made up of plural subpages. At least one of the cells includes a CPU that can request access to a data subpage. A memory manager responds to selected data access requests by (i) allocating, within the memory local to the requesting CPU, exclusive physical storage space for a data page associated with the requested subpage, and (ii) storing the requested subpage in that allocated space. The apparatus recombines data pages and deallocates them on the basis of usage and access state. The apparatus also accesses data asynchronously with respect to execution of instructions by the CPU.
