    摘要: A method and an apparatus for checking a pipelined parallel cyclic redundancy is disclosed. In accordance with the method and the apparatus of the present invention, after an entire CRC (cyclic redundancy check) logic is divided into a feedback portion and an input data portion, the input data portion is divided using a pipelined structure such that the input data portion is designed to have the pipelined structure based on an algorithm that maintains a logic level of each stage to be lower than that of the feedback portion and an algorithm that optimizes a size of a register inserted during the division to improve a speed thereof and to detect an error of a received data in a high speed data communication apparatus.

    摘要: Provided is a 4× framer/deframer module for PCI-Express and a framer/deframer device using the same. In the PCI-Express for high-rate data processing, delimiter and pad processing, and 4× framer shifting and arrangement/reverse arrangement for framing/deframing a frame format are performed to achieve a structure that facilitates reconfiguration and expansion, for example, a pipeline structure, so that the 4× framer/deframer module can operate without delay within a 250 MHz clock even when expansion to 32× is made.

    摘要: A system-on-chip (SoC) test apparatus is disclosed. The system-on-chip (SoC) testing apparatus reduces a test time due to a small amount of overhead in the case of testing an AMBA-based system-on-chip (SoC) using a TIC, an EBI, and a Test Harness, and maintains AMBA- or TIC- compatibility simultaneously while performing scan input/output operations.
