Abstract
A high-speed image signal processing system for encoding an image signal, read out at a high speed, into an encoded signal, and/or for recording a decoded signal obtained through a decoding operation on an encoded signal. The image signal, obtained through a scanning operation on an original document, is sent to an encoder through an image bus. A code bus, provided at an output of the encoder, is connected with an encoded-signal memory for storing the encoded signal. A code transfer unit, for performing input/output operation over the encoded signal and for performing transfer of the encoded signal from the code bus to a system bus, is disposed between the code bus and the system bus. A control unit, performing control over the entire system, and a document management data memory, storing management data for performing management over documents stored in the encoded-signal memory, are connected to the system bus. Further, the control unit, when receiving a request from a data input/output unit, issues a command indicative of the start of the encoding/decoding operation to the encoder/decoder. The encoder/decoder, when receiving the command from the control unit, sequentially proces…
