  • Patent number: 6615333
    Abstract: A data processing device has a circuit for correcting an effect of executing memory access instructions out of order with respect to one another in a pipeline. A detector detects whether a same memory location is addressed by a first and second memory address used to access memory for a first and second memory access instruction that are processing at a predetermined relative distance in the pipeline respectively. A correction circuit modifies data handling in a pipeline stage processing the first memory access instruction when the detector signals the addressing of the same memory location and the first and/or second memory access instruction programs a command to compensate said effect of out of order execution of the first memory access instruction with respect to said second memory access instruction.
