Packet error detecting device in a DMA transfer |
摘要 |
A packet error detecting device for detecting the existence of an error of the packet data transferred by a packet switching in a DMA transfer, comprising an operation unit formed by hardware for executing a necessary operation to detect a packet error in the packet data received in every block, a DMA controller for DMA transferring data from a memory storing the received data to the operation unit, previous to the DMA transfer of the data toward an external device, and a CPU for performing an error procedure if detecting a packet error as the result of the error detection by the operation unit.
