Debugging for DSP56800E

Using the DSP56800E Simulator

212

Targeting MC56F83xx/DSP5685x Controllers

code on a simulated DSP56800E architecture without installing any additional

hardware.

The simulator simulates the DSP56800E processor, not the peripherals. In order to use

the simulator, you must select a connection that uses the simulator as your debugging

protocol from the

Remote Debugging panel.

NOTE

The simulator also enables the DSP56800E menu for retrieving the

machine cycle count and machine instruction count when debugging.

Cycle/Instruction Count

From the menu bar of the Metrowerks CodeWarrior window, select DSP56800E >

Cycle/Instruction count

. The following window appears (Figure 8.14):

Figure 8.14 Simulator Cycle/Instruction Count

NOTE Cycle counting is not accurate while single stepping through source

code in the debugger. It is only accurate while running. Thus, the

cycle counter is more of a profiling tool than an interactive tool.

Press the

Reset button to zero out the current machine-cycle and machine-instruction

readings.
