Abstract: PURPOSE:To increase the speed of arithmetic processing in comparison with the use of a program for queuing of a pair of tokens different in length of a data processor by realizing said queuing with one instruction. CONSTITUTION:In a data synchronizing device 1, a token inputted to a firing control part 2 from a synchronous queue 14 through a signal line 21 is latched in an input token register 4, and a code table 5 and a state holding part 6 are referred by a code table address 74. The arithmetic operation in a firing control part and a processing unit of the token is prescribed by this table 5, and an operation code 30 indicates the instruction code indicating the operation in the processing unit. A firing control code 31 indicates the instruction of the operation of a control part 2 and the operation like data memory read/write of the processor can be described. A data memory base address 32 gives the base address of address calculation by which a data memory 3 is accessed with a simultaneous instruction, and a data memory buffer size 33 designates the buffer size where the token is held.

Abstract: PURPOSE:To realize the high-speed working of a data flow processor by performing the convolution processing just with a fact that N pieces of tokens to be processed make a round of an internal ring. CONSTITUTION:A link table 11, an operand fetch table 12, a data memory 13, a function table 14, a buffer queue 15, and a processing unit 16 are successively connected together in a ring form via a pipeline type bus. The tokens are transferred along said internal ring bus synchronously with the pipeline clock of a data flow processor 1. When the convolution is carried out with N pieces of data, it is possible to fetch a coefficient w(i) via the table 14 by means of a group identifier of the group tokens. Thus it is not required to make a token train produced by a token producing part 20 make two rounds of the ring bus for fetching N pieces of data and the coefficient w(i). Thus the convolution processing is performed at high speed.

Abstract: PURPOSE:To execute the instruction for renewal by respective processors after selecting a processor in parallel without aligning others and to execute a highly speedy and efficient processing by providing a processor selecting input means, a renewing means and a queuing means. CONSTITUTION:Processors 11a-11n are connected in a ring shape with a memory 13 by a ring bus 12 and the memory 13 inputs a token including picture element data through a bus 12 to a processor selecting input means 16. The means 16 sends a processor number and a data token including the picture element data to the bus 12, and the processor of the same number as the processor number inputs the data token from the means 16. Next, the contents of the data memory of the referring address corresponding to the numeric value of the picture element data through a renewing means 17 and a waiting means 18 are read, the contents are incremented and written in the data memory of the referring address. In such a case, respective processors can execute the renewing means 17 in parallel respectively and the processing can be efficiently executed at high speed.

Abstract: PURPOSE:To execute a processing at a high speed by constituting the titled system so that each part executes its processing independently in parallel with respect to input data which has been diverted by a result of a change of an identifier. CONSTITUTION:A data token which has been inputted from an external memory is reproduced to two continuous tokens by a copy instruction 31, and one of them sets the lower 3 bits as a data V by a mask operation 32, and uses an identifier (ID) change instruction 33 by a bit T=0, by which a write operation for diverting it to eight branches is executed. The other is brought to a 3-bit shift by a right shift instruction 34, and thereafter, inputted to an ID change instruction 35 by T=1, and the data V for executing the updating after the diversion is obtained.

Abstract: PROBLEM TO BE SOLVED: To disallow a third person to impersonate a recipient and to prove that an article is delivered when the article of commerce which is ordered without meeting by using a network, etc. is delivered. SOLUTION: When the article is ordered, the orderer sends one's fingerprint features from an ordering terminal 1 to an electronic commerce server 2. The electronic commerce server 2 sends the fingerprint features of the orderer and an order number to an identification terminal 3 arranged at a store, etc., that the orderer specifies as a reception destination. When a recipient makes a request to receive the article, a sales clerk of the store obtains fingerprint features of the recipient by using the identification terminal 3 and collates them with the fingerprint features of the orderer sent from the electronic commerce server 2. Only when they coincide each other, the article in handed over. Further, the identification terminal 3 sends certificate information consisting of the fingerprint features of the recipient and the order number to the electronic commerce server 2 and it is preserved in a certificate information preserving part 24.

Abstract: PROBLEM TO BE SOLVED: To attain highly accurate sorting and converging processing without extending processing time by calculating a feature level to be found out from the position of a joint line and that of a specific point. SOLUTION: A joint extracting part detects/determines the position and direction of a 1st joint line included in an inputted finger print image. A ridgeline extracting part 12 traces the ridgeline of the inputted finger print image and outputs its description. A specific point detection part 13 finds out a core specific point and a delta specific point from the ridgeline description and determines the coordinates of the position. A main pattern judging part 14 determines a pattern (main sorting) from the ridgeline description obtained from the extracting part 12 and the specific point information detected by the detection part 13. A specific point feature calculating part 15 calculates a feature level between specific points corresponding to the pattern judged by the judging part 14 based upon the specific point information and the ridgeline description. A nodal line feature calculating part 16 calculates the feature level of a specific point on a nodal line based upon the description of a nodal line approximation line, the description of the specific point position and the ridgeline description.

Abstract: PURPOSE:To provide an information processor and its processing method capable of avoiding a phenomenon that an arithmetic processing part is disabled until data loading to a register is ended and attaining high speed processing. CONSTITUTION:When an arithmetic processing part 10 for advancing processing while referring and updating a register group 11 executes an instruction for loading data necessary for operation from the external, a token generating part 12 generates a request token for commonding external loading operation, issues the token to a memory access controller 2 and sets up an unloaded flag. At the time of receiving a token including data necessary for operation, a load control part 21 stores the data in the register group 11, sets up a load completion flag and judges whether data necessary for the execution of the instruction have been loaded or not. When the data have not been completed, an instruction execution string is transferred to a token memory 13 and the execution of a new instruction string is started.

Abstract: PURPOSE:To execute parts of a process, which can be made to overlap, in parallel and to obtain a higher throughput by providing a mechanism which restarts instruction execution when return tokens from a necessary number of memories arrive after the execution of respective load instructions generating readout request tokens on condition that there is an instruction to be executed in synchronism with the end of the loading of plural data from the memories. CONSTITUTION:An arithmetic processing part 10 which performs arithmetic processing while referring to and updating a register group 11 under the control of an instruction sequence control part 14. When data are loaded in a register from an external memory, a token is generated and sent to a memory access controller. The execution of the instruction sequence is interrupted according to a sequence end flag in each instruction. A load control part 21 decides on the tokens returned from the outside whether or not a necessary number of tokens required for target load instruction execution are ready and when so, they are put in the arithmetic processing part 10 through a token memory 13 in turn, so that the previous instruction execution is carried on.
