Data processing system

A data processing system comprising:

• a bypass unit operable to output input data to either a first path or a second path;
• and
• at least one data processing unit operable to perform data processing on the data output to said second path and output processing result data;
• wherein said bypass unit is operable to, in a case where the input data are not required to be processed by said data processing unit, output the input data to said first path, which is not connected to said at least one data processing unit, and said data processing unit is operable to,
• in a case where the input data of said bypass unit are not required to be processed by said data processing unit, stop data processing.

A data processing system comprising:

• a bypass unit operable to output input data to either a first path or a second path;
• a control unit operable to control said bypass unit;
• and
• at least one data processing unit operable to perform data processing on the data output to said second path and output processing result data;
• wherein said bypass unit is operable to, in a case where the input data are not required to be processed by said data processing unit, output the input data to said first path, which is not connected to said data processing unit, in accordance with an instruction of said control unit, and said unit is operable to,
• in a case where the input data of said bypass unit are not required to be processed by said data processing unit, stop data processing by said data processing unit.
