Embodiment Construction
[0021] The technology in the present invention will be described in detail below in conjunction with the description of the drawings and the pseudo code of the algorithm. The invention mainly utilizes the powerful parallel computing ability and programmability of the graphic processor in the heterogeneous platform. Collect memory access records on the general processor side, send the records to the graphics processor side through the on-chip interconnection bus, and finally perform error detection on the graphics processor side. On this basis, the present invention utilizes: (1) Utilize Bloom filter to filter secure memory access records; (2) Avoid shared memory access from being replaced; (3) "Last write" identification simplifies detection work, these three optimization strategies Improve detection speed and detection accuracy.
