20130138919 | HIERARCHICAL MULTI-CORE PROCESSOR AND METHOD OF PROGRAMMING FOR EFFICIENT DATA PROCESSING - A multi-core processor includes a tree-like structure having a plurality of computing cores arranged in hierarchical levels, the cores all having the same logical architecture. Each core can include computing, interconnecting, and/or storage elements. The functionality of an individual element can be supplied by an entire core in a lower level. A method for programming the processor includes hierarchically decomposing an application into interconnected sub-functions, mapping the sub-functions onto groups of cores at appropriate levels of the processor, and interconnecting the mapped sub-functions so as to hierarchically compose the complete application. Sub-functions can be sequential, concurrent, and/or pipelined. Interconnections can be static or dynamically switchable under program control. Interconnect elements can also be used to implement flow control as needed in pipelined operations to maintain data coherency. The decomposing and mapping process can be iterated on sub-functions so as to optimize load balancing, software performance, and hardware efficiency. | 05-30-2013 |

20140101150 | EFFICIENT HIGH PERFORMANCE SCALABLE PIPELINED SEARCHING METHOD USING VARIABLE STRIDE MULTIBIT TRIES - A method for high speed searching of a large database provides speed, throughput, and efficient memory usage comparable to TCAM-assisted searches without using dedicated processors. Successive groups of bits from a key are processed by tables in a search tree. The tables are constructed with different sizes and types according to the structure of the key and the distribution of information in the database. Each link to a subsequent table specifies both the type of the linked table and how many key bits the table will process. The tables include, but are need not be limited to, address offset tables that use bits from the key as an addressing offset to locate a result. Embodiments are implemented on pipeline processors that include internal memory units and access to external memory. Embodiments also include string compare tables, memory mapped tables, and/or instructions to continue searching on a different memory unit. | 04-10-2014 |
