Abstract:
PURPOSE: A medical communication apparatus for a central remote monitoring system is provided to effectively control channels by enabling a user to control a channel establishment switch without changing system environment. CONSTITUTION: A converter(150) changes the frame format of a digital mode for a biometric signal collected by a PMS(Pertinent Monitoring System)(10) into an analog signal. A channel establishment switch(124) receives a selecting signal for a channel which establishes a transmission frequency band. A control unit(123) transmits channel information including the selecting signal to a PLL(Phase Locked Loop) unit(120a). A mixer(140) combines the analog signal with a local oscillation frequency.

Abstract:
A device and a method for pipelined parallel CRC are provided to detect an error from received data in a fast data communication system with improved speed by designing an input data logic part of a CRC logic in a pipeline structure based on algorithms, which lower a logic level of each step under the logic level of a feedback part and optimize size of a register inserted in division. A data XOR logic(200) uses w-bit parallel data as input. A CRC code XOR logic(230) uses n-bit CRC code feedback as the input. An XOR array(250) outputs an n-bit CRC code result by performing XOR operation of output of the data XOR logic and the CRC code XOR logic. A CRC register(240) feeds back the stored n-bit CRC code and stores the n-bit CRC code output from the XOR array as the new n-bit CRC code. The data XOR logic includes a plurality of divided data XOR logics(220a-220k) divided to lower the logic level of the divided data XOR logic under the logic level of the CRC code XOR logic, and the plurality of divided registers(210a-210k) inputting/outputting the data of the divided data XOR logics.
