public class SPU_pipeline
extends java.lang.Object

This is part of the model for of the Synergistic Processing Unit (SPU) used by the Cell broadband Engine. The information used to create this software was taken from the IBM document: "Cell Broadband Engine Programming Handbook", Version 1.1 (April 24, 2007). Currently this code only contains static information about the SPU pipeline. It is used primarily for displays and not for the actual simulation models.

Method Detail

getPipelineNumber

public static final int getPipelineNumber(java.lang.String instrName)

This method returns the pipeline number of the instruction. This should be a 1 or a 0, but will be a -1 if the instruction is not recognized.

Parameters:

instrName - the instruction mnemonic.

Returns:

This method returns the pipeline number of the instruction.

getLatency

public static final int getLatency(java.lang.String instrName)

This method returns the pipeline latency of the instruction. This will be a 0 if the instruction is not recognized.

Parameters:

instrName - the instruction mnemonic.

Returns:

This method returns the pipeline latency of the instruction.

getStalls

public static final int getStalls(java.lang.String instrName)

This method returns the number of stall cycles of the instruction. This will be a 0 if the instruction is not recognized.

Parameters:

instrName - the instruction mnemonic.

Returns:

This method returns the number of stall cycles of the instruction.
