    • A processor functioning as a coprocessor attached to a central processing complex provides efficient execution of the functions required for database processing: sorting, merging, joining, searching and manipulating fields in a host memory system. The specialized functional units: a memory interface and field extractor/assembler, a Predicate Evaluator, a combined sort/merge/join unit, a hasher, and a microcoded control processor, are all centered around a partitioned Working Store. Each functional unit is pipelined and optimized according to the function it performs, and executes its portion of the query efficiently. All functional units execute simultaneously under the control processor to achieve the desired results. Many different database functions can be performed by chaining simple operations together. The processor can effectively replace the CPU bound portions of complex database operations with functions that run at the maximum memory access rate improving performance on complex queries.
    • 用作连接到中央处理复合体的协处理器的处理器提供数据库处理所需功能的有效执行:在主机存储器系统中排序,合并,加入,搜索和操纵字段。 专用功能单元:存储器接口和字段提取器/汇编器,谓词评估器,组合分类/合并/连接单元,哈希器和微编码控制处理器都围绕分区的工作存储区居中。 每个功能单元根据其执行的功能进行流水线和优化,并有效地执行其查询部分。 所有功能单元在控制处理器下同时执行以实现所需的结果。 可以通过一起链接简单的操作来执行许多不同的数据库功能。 处理器可以通过以最大内存访问速率运行的功能有效地替代复杂数据库操作的CPU限制部分,从而提高复杂查询的性能。

    • 1. In an information handling system wherein information is represented by electrical impulse trains having the same number of impulse positions in each train, each train representing an item of information and containing impulses which are present and absent in and from said positions in a coded arrangement which varies with the item of information represented by each train, an information transfer network, means to supply impulse trains to the input to said transfer network, and checking means coupled to said transfer network, said checking means including a first counter means indicating the count of the individual trains supplied to said network, a second counter means responsive to the indIvidual impulses contained within the trains supplied to said network, and means for periodically indicating when said first and second counter means do or do not tally.
