Method for determining whether data signals of a first set are related to data signal of a second set

Claim 1

A method for controlling a vector processor so as to detect whether or not a value of each data signal among a first set of data signals has a specific relation with a value of one of a second set of data signals, the vector processor including an operation unit for performing an arithmetical or logical operation in a pipelined manner on vector data, the method comprising the steps of: (a) forming, from the first set of data signals, first vector comprised of groups of data signals, wherein said groups respectively correspond to different data signals of said first set of data signals, and data signals of each group are all equal to one data signal to which said each group corresponds among said data signals belonging to said first set of data signals and a total number of data signals of said each group is equal to a total number of data signals belonging to said second set of data signals; (b) forming, from said second set of data signals, second vector data comprised of groups of data signals, wherein data signals in each group are respectively equal to the data signals belonging to the second set of data signals and the number of the groups is equal to the number of data signals belonging to the first set of data signals; and (c) controlling the operation of said operation unit so that said operation unit determines whether or not a value of each data signal of the first vector data has a specific relation with a value of a corresponding data signal of the second vector data which is equal in vector element number to said each data signal of the first vector data thereby causing said operation unit to prvide third vector data including result data signals each indicative of a result of the determination for a pair of data signals including a data signal of the first vector data and a corresponding data signal of the second vector data; and (d) detecting, in response to the result data signals included in the third vector vector which one of the first set of data signals has a specific relation to one of the second set of data signals.

Claim 2

A method for controlling a vector processor so as to detect whether or not a value of each data signal among a first set of data signals has a specific relation with a value of one of a second set of data signals, the vector processor including an operation unit for performing an arithmetical or logical operation in a pipelined manner on vector data, the method comprising the steps of: (a) forming, from the first set of data signals, first vector comprised of groups of data signals, wherein said groups respectively correspond to different data signals of said first set of data signals, and data signals of each group are all equal to one data signal to which said each group corresponds among said data signals belonging to said first set of data signals and a total number of data signals of said each group is equal to a total number of data signals belonging to said second set of data signals; (b) forming, from said second set of data signals, second vector data comprised of groups of data signals, wherein data signals in each group are respectively equal to the data signals belonging to the second set of data signals and the number of the groups is equal to the number of data signals belonging to the first set of data signals; and (c) controlling the operation of said operation unit so that said operation unit determines whether or not a value of each data signal of the first vector data has a specific relation with a value of a corresponding data signal of the second vector data which is equal in vector element number to said each data signal of the first vector data thereby causing said operation unit to prvide third vector data including result data signals each indicative of a result of the determination for a pair of data signals including a data signal of the first vector data and a corresponding data signal of the second vector data; and (d) detecting, in response to the result data signals included in the third vector vector which one of the first set of data signals has a specific relation to one of the second set of data signals.

Claim 5
