Method Detail

main

public static void main(java.lang.String[] args)

This enables the stand-alone assembler and disassembler. The command line should be either: java MicroBlaze -dasm or java MicroBlaze -asm

Parameters:

args - the command line arguments.

reset

public void reset()

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

Overrides:

reset in class Processor

preExecute

public void preExecute(int instr)

Description copied from class: AutoModel

This method is called immediately before execution and may be overloaded to do things like save instruction field values to locals.

Overrides:

preExecute in class AutoModel

Parameters:

instr - The instruction

postExecute

public void postExecute(int instr)

Description copied from class: AutoModel

This method is called immediately after execution and may be overloaded to do things like save instruction field values to locals.

Overrides:

postExecute in class AutoModel

Parameters:

instr - The instruction

setFslIn

public void setFslIn(int i,
                     int mmioAddr)

This method is used to set the FSL inputs.

Parameters:

i - The FSL input number (0 - 7)

mmioAddr - the Memory Mapped IO address.

setFslOut

public void setFslOut(int i,
                      int mmioAddr)

This method is used to set the FSL outputs.

Parameters:

i - The FSL output number (0 - 7)

mmioAddr - the Memory Mapped IO address.

op

protected static AutoModel.Decode op(int a)

This is just a simple helper function used in decoding basic TypeB instructions. It mostly just makes the Instruction table easier to read.

Parameters:

a - The code for the opcode field.

Returns:

This method returns a decode array for an instruction.

op

protected static AutoModel.Decode op(int a,
                                     int b)

This is just a simple helper function used in decoding basic Type A instructions. It mostly just makes the Instructiontable easier to read.

Parameters:

a - The code for the primary opcode field.

b - The code for the secondary opcode field.

Returns:

This method returns a decode array for an instruction.

opGet

protected static AutoModel.Decode opGet(int a,
                                        int b)

This is just a simple helper function used in decoding get instructions. It mostly just makes the Instructiontable easier to read.

Parameters:

a - The code for the Ra opcode field.

b - The code for the secondary opcode field.

Returns:

This method returns a decode array for an instruction.

opPut

protected static AutoModel.Decode opPut(int a,
                                        int b)

This is just a simple helper function used in decoding put instructions. It mostly just makes the Instructiontable easier to read.

Parameters:

a - The code for the Rd opcode field.

b - The code for the secondary opcode field.

Returns:

This method returns a decode array for an instruction.
