Title: Communication controller
Inventor: HORIE YASUO
IPC: H04L69/40
Filed: 1985-11-26
Abstract: PURPOSE:To discriminate the number of types of received packets at the incoming time point of a control field by transmitting the incoming of the received packet to a CPU at a time point when the information related to protocol control, etc. during reception of the packet is detected and shifting to the protocol control. CONSTITUTION:The incoming of a received packet is detected by a communication control circuit 4 and informed to a CPU 1. Then a DMA control circuit 7 is started to transfer the received data to a RAM 6 according to a DMA request produced by the circuit 4 in response to the reception of the packet. When the data on a control field is transferred to the RAM 6, this transfer of data is detected by a control field ADR DEC 12 and an interruption request is instructed to an interruption control circuit 2. The circuit 2 applies an interruption to the CPU 1. Then a control field converting circuit 10 shifts the control to a processing routine corresponding to the control field stored in a jump address given by a converted interruption vector. Thus the protocol control processing is carried out.
