Hi, like I wrote some weeks ago, the SHARC's have two registers, which are counting the cycles. These are the ones which are used by the debugger. They don't have syntaxhiglighting, but they are accessible by the assembler. So you can reference them via asm (). They are called emuclk and emuclk2 and they form a 64-Bit cycle counter. You can check and have a try with the debugger. regards Christoph ---------------- m.u.t GmbH DSP engineering & software development Christoph Ripcke Am Marienhof 2 22880 Wedel, Germany mail: mailto: phone: +49-4103-9308-38 fax: +49-4103-9308-7038 ---------------- -----Ursprgliche Nachricht----- Von: P Narayanaswamy [mailto:] Gesendet: Donnerstag, 13.
