Abstract: 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.

Abstract translation: 在支持条件写入处理操作的数据处理系统中，提供垃圾寄存器，使得当遇到非写入条件时，对垃圾寄存器进行寄存器写入，而不是由条件写入操作指定的数据寄存器。 因此，与寄存器写入是否发生相关联的功率签名被屏蔽。 垃圾寄存器活动可以通过存储在系统配置寄存器中的配置参数来编程启用和禁用。

Abstract translation: 在支持有条件写入处理操作的数据处理系统内，提供垃圾寄存器，使得当遇到非写入条件时，寄存器写入垃圾寄存器，而不是由寄存器写入由垃圾寄存器指定的数据寄存器 有条件的写操作。 因此，与寄存器写入是否发生相关的功率签名被屏蔽。 垃圾寄存器活动可以通过存储在系统配置寄存器中的配置参数来编程启用和禁用。
