Method for using a low-power consumption, high performance, wireless and networking products processor microarchitecture mini-data cache for data collection

Method for using a low-power consumption, high performance, wireless and networking products processor microarchitecture mini-data cache for data collection. Benefits include improved performance.

Background

        � � � � � The conventional method uses the following procedure (see Figure 1):

1.        � � Collect data
2.        � � Fill the buffer
3.        � � Dump the buffered data to a disk

Description

        � � � � � The disclosed method is the use of the mini-data cache of a low-power consumption, high performance, wireless and networking products processor to save profiling information (see Figure 2) generated by the power management unit (PMU). Because the mini-data cache is relatively small, the profiling data should be compressed into as compact a space as possible without degrading performance.

Advantages

        � � � � � The disclosed method provides advantages, including improved performance due to the interrupt service routine only occasionally have to go out to external memory, which is much slower than cache memory.
