Instruction Simulation

The µVision Debugger provides complete instruction set simulation for all ARM7, ARM9, Cortex-M3, XC16x, C16x, ST10, 251, and 8051 devices.

When debugging your program, op-codes are interpreted and executed as their corresponding instructions would be. You may view program disassembly in mixed mode or in assembly code.

All registers and flags are updated as each instruction executes. Results display in the Register Tab of the Project Workspace.

As you step through your program, affected registers are highlighted.

Instruction timings are accurately simulated so you can easily determine how long a function or module takes to execute. Timing is cycle-accurate for deterministic parts.
