Class GenInterpreter

java.lang.Object
  avrora.sim.BaseInterpreter
      avrora.sim.GenInterpreter

All Implemented Interfaces:

InstrVisitor, IORegisterConstants, State

public class GenInterpreter

extends BaseInterpreter

implements InstrVisitor

The GenInterpreter class is largely generated from the instruction specification. The framework around the generated code (utilities) has been written by hand, but most of the code for each instruction is generated. Therefore it is not recommended to edit this code extensively.

Constructor Detail

GenInterpreter

protected GenInterpreter(Simulator s,
                         Program p,
                         int flash_size,
                         int ioreg_size,
                         int sram_size)

The constructor for the Interpreter class builds the internal data structures needed to store the complete state of the machine, including registers, IO registers, the SRAM, and the flash. All IO registers are initialized to be instances of RWIOReg. Reserved and special IO registers must be inserted by the getIOReg() and setIOReg() methods.

Parameters:

p - the program to construct the state for

flash_size - the size of the flash (program) memory in bytes

ioreg_size - the number of IO registers

sram_size - the size of the SRAM in bytes
