Maik Merten 52f4e9a00f enforce that the address range of devices falls within the address range of the bus. Turned out that the CPU tests instantiate memory with the last parameter as memory size, not end address (fixed now). Also make sure that the address lookup array takes the offset caused by non-zero starting addresses into account. 2014-07-25 21:24:16 +02:00

Seth Morabito bc3de80892 Execution Trace Log
Introduces an execution trace window that will keep track of the most
recent 10000 execution steps. I'm not entirely happy with the
implementation, yet.

Seth Morabito a1d07bf223 First work toward moving to a Swing UI for the simulator. 2012-04-22 20:49:18 -07:00
sethm a3e57274a2 - Major overhaul of the Simulator control class (where 'main' lives).
- Removed the CommandParser class entirely, as the weird dependency between
  Simulator and CommandParser never made me comfortable.
- Added a Command inner class to Simulator that handles some of the
  command line tokenizing.

Seth J. Morabito ac88786df7 - Continued refactoring of address decoding.
- Device read and write may now throw MemoryAccessException, and appropriate
  throws clauses have been added throughout the code.
