Zusammenfassung:An apparatus and method of operating a data processing apparatus are provided. The data processing circuitry is responsive to a hint instruction to then assert at least one performance modifying control signal, when subsequently generating control signals for other data processing instructions. This causes the data processing functional hardware which performs the data processing operations defined by the data processing instructions to operate in a modified manner, although the data processing results produced do not change in dependence on whether the at least one performance modifying control signal is asserted. 提供了一种装置和一种操作数据处理装置的方法。数据处理电路响应于提示指令以在随后针对其他数据处理指令生成控制信号时,断言至少一个性能修改控制信号。这使得执行由数据处理指令定义的数据处理操作的数据处理功能硬件以修改的方式操作,尽管所产生的数据处理结果不会根据至少一个性能修改控制信号是否被断言而改变。
