Introduction
TriCore is a unified, 32-bit microcontroller-DSP architecture optimized for real-time embedded systems. It mostly targets gasoline and diesel engine control units (ECUs), applications in hybrid and electric vehicles as well as transmission, active and passive safety and chassis applications. The instruction set architecture (ISA) consists of three types of instruction sets: one microcontroller, one RISC load-store, and one DSP instruction set -- thus the name TriCore.
Status

Build Directions
./configure --target-list=tricore-softmmu && make
Running a binary
qemu-system-tricore -M tricore_testboard -kernel /path/to/your/binary
Please note that there is no real existing TriCore board implemented so far. The suggested testboard only instantiates memory and a CPU, and thus no I/O is possible.
Attaching gdb
If you use gcc to build your guest binary, make sure you build using the old debug symbols. The flags for gcc are
-gdwarf-2 -gstrict-dwarf
Now you can start QEMU
qemu-system-tricore -M tricore_testboard -kernel /path/to/your/binary -s -S
QEMU will halt until you attach with the tricore-gdb
(gdb) target remote localhost:1234
