4X FRAMER-DEFRAMER MODULE FOR PCI-EXPRESS AND 4X FRAMER-DEFRAMER DEVICE USING THE SAME |
摘要 |
A 4X PCI(Peripheral Component Interconnect)-Express frame conversion module and a 4X PCI-Express frame conversion device using the same are provided to perform arrangement/rearrangement for 4X frame conversion, and frame format formation/deconstruction as well as delimiter and pad processing in 4X PCI-Express for fast data processing, thereby facilitating reconfiguration and extension. A framing input data receiver(210) receives a 32-bit data input signal. A shifter(230) outputs a 24-bit shift signal and an 8-bit shift-out signal, which is the LBS(Location-Based Service) of the 32-bit data input signal, by shifting the 32-bit data input signal. A basic framing signal generator(250) generates a 32-bit basic framing signal by receiving/assigning the 8-bit shift-out signal as the MSB(Most Significant Bit) and adding the 24-bit shift signal of the shifter. A framing controller(270) generates a framing control signal controlling insertion of a delimiter or a pad character into the basic framing signal. A framing data output unit(290) outputs a 32-bit PCI-Express format signal by operating the basic framing signal based on the framing control signal. The framing controller connects and inputs the 8-bit shift-out signal as an 8-bit shift-in signal.
