# mico32

LatticeMico32 instruction set simulator project







Includes a C/C++ model of the lm32 CPU, with the following features:

* All supported core instructions

* All h/w modelled for configurable instructions

  - Multiplier

  - Divider

  - Sign extender

  - Barrel shifter

* Configurable internal memory

* All h/w debug break- and watchpoints modelled

* Cycle count functionality

* Configurable 'hardware', as per the Mico32

* Run-time and static disassembly

* Data and Instruction caches for timing model

* Optional MMU capability, via Data and Instruction TLBs

* Extensibility via callbacks

  - Intercept memory accesses

  - Regular callback with ability for external interrupt generation

  - JTAG register access callback

* Configurable user defined execution break points

  - On a given address

  - After a single step, or clock tick

  - After a fixed number of cycles

  - On 'hardware' debug break point

* Access to internal Memory

* Access to internal state

* Compatible with Lattice Semiconductor GNU tool chain (lm32-elf-xx)

* Both C++ and C linkage interfaces available

* Separate GDB remote debug interface code is included

  - Supports both virtual serial and TCP socket connections

There are build options for MSVC 2010, CYGWIN and Linux, and an embedded Linux system model case study. A Python3 GUI is also bundled for configuring and running cpumico32, and a GDB remote target interface is available for non-intrusive debug.
