Abstract
A data processing system includes a buffer, a design under checking (DUC), and a self-checking circuit. The buffer is used to buffer data generated from a source device. The DUC is used to perform a designated function upon data read from the buffer when operating under a normal mode. The self-checking circuit is used to apply logic functional checking to the DUC when the DUC operates under a self-checking mode. When the DUC operates under the self-checking mode, the buffer keeps buffering data generated from the source device.
Claims18
A data processing system comprising:
- a buffer, arranged to buffer data generated from a source device;
- a design under checking (DUC), arranged to perform a designated function upon data read from the buffer when operating under a normal mode;
- and
- a self-checking circuit, arranged to apply logic functional checking to the DUC when the DUC operates under a self-checking mode;
- wherein when the DUC operates under the self-checking mode, the buffer keeps buffering data generated from the source device.
A data processing method comprising:
- performing, by a design under checking (DUC), a designated function upon data read from a buffer when the DUC operates under a normal mode;
- and
- when the DUC operates under a self-checking mode:
- applying logic functional checking to the DUC;
- and
- keeping buffering data generated from a source device in the buffer.
