+When ever you have to make a new NIOS CPU configuration you can use this table
+as a reference list to the original NIOS SDK symbols made by Alteras SOPC
+Builder. Look into excalibur.h and excalibur.s in your SDK path cpu_sdk/inc.
+Symbols beginning with a '[ptf]:' are coming from your SOPC sytem description
+(PTF file) in sections WIZARD_SCRIPT_ARGUMENTS or SYSTEM_BUILDER_INFO.
