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.
