+= Processor Functional Description =
+
+This hardware component is a lm32 (lattice mico32) processor core.
+
+This ISS uses the [wiki:Component/Iss2Api ISS2 API]
+and can be wrapped in a CABA or TLM-T [wiki:Component/VciXcacheWrapper Wrapper].
+ * [wiki:Tools/GdbServer gdb server] support is under development.
+
+It implements all instructions defined in the lm32 architecture specification.

+
+== Interrupts ==
+
+LM32 architecture supports up to 32 external interrupt lines. This ISS implements all these interrupt lines by default.
+
+== Ports ==
+
+None, it is to the wrapper to provide them.
+
+= Notes =
+
+== MMU suppurt ==
+The lm32 provided by lattice does not have an mmu. 
+
+== Compiling programs for lm32 with SoCLib ==
+
+Before compiling a program for the lm32 with the SoCLib framework you will need to define some system variables (usually on the ~/.soclib/soft_compilers.conf) needed to find the lm32 compiler. Below you have an example:
+{{{
+sparc_CC_PREFIX = lm32-elf-
+sparc_CFLAGS = -O2 -g -mmultiply-enabled -mdivide-enabled -msign-extend-enabled -mbarrel-shift-enabled
+sparc_LDFLAGS = -nostdlib
