    • A method of operating an integrated circuit involves supplying an instruction portion of a command to the integrated circuit to specify an operation to be performed by the integrated circuit. At least some types of commands also include an attributes portion that provides additional information about the operation to be performed. The attributes portion of the command is supplied to the integrated circuit with a delay relative to the instruction portion of the command. The integrated circuit selectively enables circuitry for processing the attributes portion if the integrated circuit determines from the received instruction portion that the command also includes an attributes portion. The delay between the two portions of the command provides sufficient time for the integrated circuit to enable the attributes processing circuitry, which, in a default state, can be disabled during an active mode of the integrated circuit to save power.
    • 一种操作集成电路的方法包括向集成电路提供命令的指令部分,以指定要由集成电路执行的操作。 至少一些类型的命令还包括提供关于要执行的操作的附加信息的属性部分。 命令的属性部分相对于命令的指令部分延迟地提供给集成电路。 如果集成电路从接收到的指令部分确定该命令还包括属性部分,则集成电路选择性地启用用于处理属性部分的电路。 该命令的两个部分之间的延迟为集成电路提供了足够的时间,使得能够在集成电路的活动模式期间在默认状态下禁用属性处理电路以节省功率。
