<p>The present invention relates to a method for organising on-chip data memory in an embedded system-on-chip platform whereon a deterministic application is run having to meet at least one guaranteed constraint on its functional system behaviour. The method comprises the steps of
- dividing the deterministic application into a plurality of blocks, at least one block corresponding to at least a part of a subtask of the deterministic application, said at least one block receiving input data and/or generating output data and comprising internal intermediate data for transforming the input data into the output data,
- splitting the internal intermediate data into state data and non-state data, said state data depending on previous internal intermediate data and non-state data being directly used inside the execution of one subtask, and
- putting the non-state data and at least a part of the state data in protected buffering means being part of the data memory, said buffering means provided with means for error detection and correction, so that they are available for mitigating the effect of faults on the functional system behaviour on-line while meeting the at least one guaranteed constraint.</p> |
