Abstract: 본 발명은 캐리 예측(CLA : Carry Look-Ahead) 가산기에 관한 것이다. 캐리 예측 가산기는 일반적으로 4비트 단위로 구성되고, 각 4비트 캐리 예측 가산기는 캐리 예측 발생기와 결합하여 더 큰 단위의 입력 신호를 처리할 수 있는 캐리 예측 가산기가 구성된다. 본 발명의 캐리 예측 가산기에서는 내부의 캐리를 생성할 때 캐리 발생 함수와 캐리 전달 함수를 이용하지 않고 각 비트에 대한 캐리를 전단 비트의 캐리를 이용하여 순차적으로 계산함으로써, 어느 정도의 전파 지연은 감수하면서 논리 게이트 회로를 단순화시킬 수 있다.

Abstract: PURPOSE: A block coding apparatus capable of changing a high-speed session and a method for driving the same are provided to reduce a delay time due to a session change by performing a series of operations for a session change at high speed using hardware of the block coding apparatus. CONSTITUTION: A host matching unit(200) performs a standard matching function of a host. A local bus arbitrator(201) transmits instruction data and coding/decoding processing data inputted from the host and transfers coding/decoding result data and response data to the host. An instruction interpreter(207) analyzes the instruction data from the host. If the instruction data is coding/decoding processing instruction, the instruction interpreter(207) generates response data to transmit it to the host matching unit(200), and otherwise, it transmits variables required to the instruction data and a coding/decoding processing to instruct the start of a coding/decoding processing operation. A CPU(Central Processing Unit) generates response data corresponding to the instruction performance result. A code chip receives the variables from the instruction interpreter(207) to realize a block code algorithm and to perform a block coding or decoding operation. A session data memory stores data of a session key, an initialization vector, an operation mode, a condition of a session. Input/output buffer memories temporarily stores the coding/decoding processing data from the host and the coding/decoding processing result data of the code chip.

Abstract: PURPOSE: A circuit for controlling a data transmission is provided to control a wait inter-exclusively upon transmitting data between two CPUs driven individually. CONSTITUTION: In a circuit for controlling a data transmission, the first signal comparing section(310) compares the write signal(WR_a) of the first CPU with the read signal(RD_b) of the second CPU to determine whether an error is generated or not upon transmitting data from the first CPU to the second CPU. The second signal comparing section(320) compares the write signal(WR_b) of the second CPU with the read signal(RD_a) of the first CPU to determine whether an error is generated or not upon transmitting data from the second CPU to the first CPU. A signal operation section(330) outputs a ready signal for controlling the continuous writing and reading operations in the first and second CPUs by operating the output signals of the first and second signal comparing sections.
