Hi, I am about to start a ADSP project and wonder what debugging tools to go for. The card is to be designed from scratch and will have a USB-interface for data exchange between the ADSP and a PC. Molding the JTAG interface into the USB-interface, as on the EZ-kits, would increase the chip count (and cost), so the most attractive solution seems to be one of AD's emulators with a 14-pin JTAG connector and USB-connector on the PC end. However, I am not sure which one to go for. Anybody that have used the background telemetry channel of teh USB 2.0-based HP emulator? According to the gloss it is "a non-intrusive way of exchangeing data without affecting the target system's real-time characteristics". What that means in practical use is not so clear, though, so it would be very useful to hear from somebody that have used it in a real project. Is it worth paying the additional price? Actually, I haven't checked the prices yet, so I am not sure how much expensive it is. Best regards C.C. -- _____________________________________________________________ Web-based SMS services available at http://www.operamail.com. From your mailbox to local or overseas cell phones.

We have a new ADI HP emulator but we haven't had a chance to use the background telemetry feature. One of the advantages of the HP emulator is that it is fast. It uses a USB 2.0 interface operating in the high speed (480Mb/s) mode. It is also expensive, about $4000 in the US. ADI also has a slower general purpose emulator that is now available for $1200. You haven't mentioned which DSP you are targeting. We sell the BeastRider Debugger. They are low cost emulators ($600) that support the SHARC family of DSPs (2106x, 2116x, 21262). An assembler and linker are included.
