Abstract: Eine Verarbeitung, die unter Verwendung eines CAM durchgeführt wird, außer wenn ein Fehler in Daten auftritt, die in dem CAM gespeichert sind, kann auch dann fortgesetzt werden, wenn ein Fehler in den im CAM gespeicherten Daten auftritt. Einem Komprimierungsdatenpfad und einem Dekomprimierungsdatenpfad wird ein eingegebener Zeichencode bereitgestellt. In dem Komprimierungsdatenpfad gibt eine Schaltung 21 zum Suchen von wiederholten Daten eine Übereinstimmungsadresse einer Zeichenfolge in dem CAM und ein Zeichenfolge-Übereinstimmungssignal aus, das die Übereinstimmung der Zeichenfolge in dem CAM angibt. In dem Dekomprimierungsdatenpfad ermöglichen es die Flipflops 1001 bis 1004 dagegen, dass ein Zeichencode ohne Änderung weitergeleitet wird. Eine Auswahlvorrichtung 98 gibt die Übereinstimmungsadresse von dem Komprimierungsdatenpfad und die Anzahl von aufeinanderfolgenden Ausgaben des Zeichenfolge-Übereinstimmungssignals aus, wenn kein Paritätsfehlersignal von der Schaltung 21 zum Suchen von wiederholten Daten ausgegeben wird und die Anzahl der aufeinanderfolgenden Ausgaben des Zeichenfolge-Übereinstimmungssignals größer als oder gleich 3 ist; andernfalls gibt die Auswahlvorrichtung 98 den Zeichencode von dem Dekomprimierungsdatenpfad aus.

Abstract: A process performed using a CAM when an error is not generated in the data stored in the CAM, can be continued even if an error is generated in the data stored in the CAM. An input character code is provided to a compressed data path and a non-compressed data path. In the compressed data path, a repeat data retrieval circuit (21) outputs a coincident address of a character string in the CAM and a character string coincident signal which indicates the coincidence of the character string in the CAM. On the other hand, in the non-compressed data path, flip-flops (1001 to 1004) send the character code without any changes. A selector (98) outputs the coincident address and the number of consecutive outputs of the character string coincident signals from the compressed data path if a parity error signal is not output from the repeat data retrieval circuit (21) and the number of consecutive outputs of the character string coincident signals is three or greater, and if not, outputs the character code from the non-compressed data path.

Abstract: The objective of the present invention is to effectively detect a longer character string from among objects to be searched such that a plurality of character strings of different lengths having the same portion exist therein. The present invention includes: a repeated data search circuit (21) which, with a certain character as a starting point, assesses a consecutive match between character data which have been input and character data within a CAM cell array (26) in order to output OFRB-0, which indicates the presence or absence of the consecutive match, and MADR-0, which indicates the address of the consecutive match; and trace circuits 1001, , 100K, which assess consecutive matches with characters which have been shifted by one character each as starting points in order to output OFRB-1, , OFRB-K, which indicate the presence or absence of the consecutive matches and MADR-1, , MADR-K, which indicate the addresses of the consecutive matches. Then, the circuit which has output the signal that was the longest consecutive match among the OFRB-0, , OFRB-K is identified, and the address among MADR-0, , MADR-K which was output by the circuit is used as the address of the longest matching character string.

Abstract: An improved wireless information processing apparatus that is connectable to an appropriate one of the access points prepared by an internet provider even under a mobile environment is disclosed. When a user of this terminal requests connection to the Internet, this terminal extracts a CS-ID from notification information transmitted from a wireless base station and, then, retrieves its own association table to acquire a telephone number of an access point nearest to the current location. Then, this terminal dials-up to the acquired access point to establish an internet connection. As a result, this terminal is allowed to download an electronic mail destined therefor, a Web page (HTML file or the like) stored in a disk of a given Web server and the like. Alternatively, this terminal is allowed to transmit data contained therein (or a file and/or an electronic mail edited on this terminal) to another computer system connected to the Internet, or to upload such data to a disk of a given Web server.

Abstract: To provide an improved wireless information processing apparatus that is connect able to an appropriate one of the access points prepared by an internet provider even un der a mobile environment. When a user of this terminal requests connection to the Inte rnet, this terminal extracts a CS-ID from notification information transmitted from a wirel ess base station and, then, retrieves its own association table to acquire a telephone nu mber of an access point nearest to the current location. Then, this terminal dials-up to th e acquired access point to establish an internet connection. As a result, this terminal is allowed to download an electronic mail destined therefor, a Web page (HTML file or the like ) stored in a disk of a given Web server and the like. Alternatively, this terminal is al lowed to transmit data contained therein (or a file and/or an electronic mail edited on t his terminal) to another computer system connected to the Internet, or to upload such data to a disk of a given Web server.
