Trace_Mapper
Mappers / Trace_Mapper
Code File Location: VisualSim/actor/lib/Trace_Mapper
o This block enables the mapping of Software Traces to Hybrid Processor.
This block
reads the parsed GEM5 output file (*.csv) as a parameter. This csv
contains the I_Cache addresses, Instruction sequences and D_Cache
addresses. When an input data structure comes in, along with the input
data structure, Trace_Mapper sets the required fields (A_Instruction ,
A_I_Addr and A_D_Addr) and send the request to the processor. This is
done for each line in the csv. When one line completes execution from
the processor, the Processor returns the data structure back to the
Trace_Mapper. Once the data structure returns, Trace_Mapper reads the
next line and sets the required fields and send it to the Processor.
This process repeats until the End Of File is reached. When the End Of
File is reached, the Trace_Mapper sends the data structure on the
output port.
| Parameter | Explanation | Type | Example |
| fileOrURL | This
parameter is used to read the input csv file which contains the
executed instruction traces, I_Cache_Address and D_Cache_Address. This csv file ( which is to be linked to this parameter) is obtained by parsing the GEM5 output file using the python parser provided by VisualSim Architect. |
String | "./dhrystone_a77_2k.csv" |
| Target_Processor | Used to specify the Name of the Processor to which the traces will be sent for execution | String
or Field |
"ARM_Cortex_A77"
or input.A_Destination (field name of user's choice) |
| Debug_Mode | If
this parameter is set to be true, then debug statements will be printed
out on the commandline. |
Booelan | true Following screenshot shows the type of information that will be printed out in the commandline:  |
| Port | Explanation |
| input | The input port. |
| output | The output port. |
