The in-circuit-emulator BICEPS for ARM based microcontrollers is a professional real-time debugging tool. It expands standard JTAG debugging by real-time trace features. A port emulation unit rebuilds port signals during program execution: no pins are lost for debugging signals.

The BICEPS real-time trace memory

An important feature of the BICEPS emulator is the real time trace memory. Running at full system speed, the BICEPS records all opcodes executed by the ARM controller.

The trace memory contents can be presented on source text or assembler level or in a mixed mode.

A special context mode shows the trace memory cursor in the source text and allows stepping forward or backward like executing single steps in two directions (see datasheet).

Using a real-time trace means first-class debugging. Additional information like the time stamp for each executed program line give you hints you can't get by other tools. For example: let the debugger calculate the time differences between interrupt calls and see at once, that the interrupt service routine lasts too long in 1 of 20 cases. This is real real-time debugging !
