Processing activity masking in a data processing system |
摘要 |
Within a data processing systems supporting conditional write processing operations, a trash register is provided such that when non-write conditions are encountered a register write is made to the trash register rather than the data register specified by the conditional write operation. Thus the power signature associated with whether or not a register write does or does not occur is masked. The trash register activity may be programmable enabled and disabled by a configuration parameter stored within a system configuration register.
