winIDEA HelpDisassemble Cadence Extended Xtensa Cores with winIDEA
In this topic:
Introduction
Cadence Extended Xtensa Cores are a family of customizable processor cores designed to meet the specific needs of various applications, particularly in the embedded systems and digital signal processing (DSP) domains. winIDEA supports disassembling the Cadence extended Xtensa cores using external libraries DLLs.
|
The default SFR and additional SFR folder structure should match. For example, default SFR folder structure SFR/ARM/CPU/; and additional folder MyAdditionalSFRsARM/CPU/. |
|
For the BBE32E core, the following DLL files should be included: xtisa-msvc.dll, libisa-core.dll, libisa-core-hw.dll, libisa-radar24.dll. For other cores and inspection contact via Technical Support. |
Requirements
•winIDEA version 9.21.206 or higher
•Specific DLL files
•Matching default SFR and additional SFR folder structure
Configuration
To disassemble the extended Xtensa cores, you have to use the DLL files and place them to the correct location.
|
Open View / Debug / SFRs / Special Function Registers / right-click on the device / Properties. |
This will display the location of the default SFR used for the current device, in this case %workspace%/SFR/ARM.
|
Create an additional folder in your workspace folder, e.g. MyAdditionalSFRs/ARM. |
|
Link the folder via Tools / Options / SFRs / Custom / Use in addition to the default database. |
This is now a folder that winIDEA will scan for the DLLs for a specific device.
|
To complete the path to the additional SFRs open Help / Display Option. |
|
Check iOPEN and search for "dll". |
You get the JSON format data. Under DasmDLL you see the folder name (e.g. CPU) needed for the DLLs to be found. In this case, the complete path of the additional SFR database containing the external library DLLs would be: %workspace%/MyAdditionalSFRs/ARM/CPU/.
|
Add a subfolder to MyAdditionalSFRs/ARM. |
|
Add the DLL files. |
|
Perform download. |
|
If DLL files don’t exist or are in any way unusable, winIDEA will log this and switch to the internal disassembler. In this case, the extended ISA instructions will not be recognized and marked accordingly in the Disassembly window. To see logs, enable the logging option (20) SFR. |
