Method Detail

decode

public int decode(int instr)
           throws IllegalOpcodeException

Description copied from class: Processor

A unique code identifying the instruction is returned by this method. In some processors with simple fixed-field opcodes this may be a very simple method to define. Other architectures with more complex decoding will require a more complex implementation.

Specified by:

decode in class Processor

Parameters:

instr - The instruction to be decoded.

Returns:

A unique code identifying the instruction is returned by this method.

Throws:

IllegalOpcodeException - if an illegal opcode is encountered.

execute

public void execute(int instr)
             throws MemoryAccessException,
                    IllegalRegisterException

Description copied from class: Processor

This method is called after the fetch() and decode() and represents the execution phase of the instruction. All update of processor state occurs in this method. This is where most of the processor definition will occur. See examples for suggestions on implementation of this method.

Specified by:

execute in class Processor

Parameters:

instr - The instruction to be executed.

Throws:

MemoryAccessException - A Memory Access Exception is thrown is an illegal memory access is attempted.

IllegalRegisterException - if an attempt is made to access a register illegally.

getPC

public int getPC()

Description copied from class: Processor

This method returns the current Program Counter.

Specified by:

getPC in class Processor

Returns:

This method returns the current Program Counter.

setPC

public void setPC(int pc)

Description copied from class: Processor

This method sets the current Program Counter.

Specified by:

setPC in class Processor

dasm

public java.lang.String dasm(byte[] instr)

Description copied from class: Processor

This method disassembles an instruction. Note that a byte array is provided as the interface. This is to make this method as generic as possible.

Specified by:

dasm in class Processor

Parameters:

instr - The instruction to be disassembled.

Returns:

This method returns the disassembled instruction.

reset

public void reset()

This method resets the MicroBlaze processor. Note that super.reset() must me called to completely intialize the processor.

Overrides:

reset in class Processor
