Examine the captured trace in the Trace tab:
All the data access are included in the captured trace.
Search for the first instance of
SendData:Click the Trace tab to display the captured trace.
Select Find Symbol Name... from the Find menu to display the Enter Value dialog box.
Enter SendData.
Click Find. The dialog box closes, and the first instance of
SendDatain the captured trace is selected. Figure 10.46 shows an example. RealView Debugger generates a TRACEBUFFER CLI command, which is also displayed in the Cmd tab of the Output view, for example:tracebuffer,gui,find_addr=0x000080A8..0x00008107Scroll through the captured trace to view the next two data trace samples. Figure 10.47 shows an example. In this example, the read accesses from elements 1085 and 1086 are used to compute
num_xmit(line 212 intrace.c).Click the trace.c tab in the Code window to see the corresponding line of source. Figure 10.48 shows an example.
Scroll down the trace until elements 10346 to 10373 are visible:
Elements 1089 to 1092 (
W Data) show how the header value (0xAAAAAAAA) is written to*output_fifo(0x20000).Elements 1093 (
Exec) to 1097 (W Data) show how the value ofaverage(0xFFFFF9B5) is written to*output_fifo(0x20000).The variable
averageis stored at0xA1D4, shown in the sample at element 1095.
Figure 10.49 shows an example.
Search for elements of interest:
Make a note of the address of
average, given by&averagein the Watch view.Select Find Address Expression... from the Find menu in the Analysis window to display the Enter Value dialog box.
Enter the address of
average, 0xA1D8 in this examlple.Click Find. The dialog box closes, and the first element with the address
0xA1D8is selected.Scroll up through the trace until you see the start of the
GetAverage()function.The traced data accesses for
GetAverage()show all the reads from theinput[]array, ending in a write toaverage.
