Hi all, I am new to DSP processor. I need to work on ADSP-2188. I would like to what is an emulator is? and how is it helpful in designing DSP systems? Thanks __________________________________________________ |

You download code via a simple terminal program such as HyperTerminal.

hi all, i am working on adsp 2192-12 processor and using visualDSP IDE version 3.0.1.1. i am using c compiler for 219x compiler: cc219x ver 5.0.6 and assembler : ADSP 219x ELF assembler 2.0.4.0 ver. linker : ADI DSP linker 2.3.3.1 ver. the problem is that all the i/o operations like printf,scanf,fopen,fscanf,... are not working in my c code. while compiling i am getting the following error: [Error E2007] symbol '_fopen' referenced in file 'C:\USER\test\DEBUG\test.DOJ' could not be resolved and so on....for the other i/o commands also. can you please help me as to what is the problem? is the problem with the visualDSP IDE version 3.0.1.1. or any programming fault? waiting for your replies thanks |

An Emulator (in circuit emulator or ICE from short) is a debug tool. The ICE plugs into a special serial ice port on the ADSP218X line of DSP's and allows you to inspect and change program and data memory and all the registers, load code and execute it and set breakpoints and single step. Extremely valuable for debugging in hardware, on a real DSP system. The ICE consists of a hardware pod that connects the dsp-under-test to a PC and PC software that formats the contents of the DSP and puts it on the PC's monitor where you can see it and change it. A simulator, is a PC program that pretends to be the DSP under test. Quite useful in debugging DSP software, you can inspect and change and single step. Simulator's are quite accurate, and a DSP program that produces the correct answers under simulation is quite likely to work properly in hardware. An eval board (EZkit) is a small test board with the DSP and usually an audio codec upon which you can run DSP programs. Eval boards come with most (but not all) the software tools you need to write simple programs. If you are just getting started, and have budget constraints, start with an eval board. You can try out simple programs and see what happens. However debugging on an eval board without the ICE is harder, the eval board won't tell you WHY the software doesn't work, just that you have trouble. If you are trying to build a real project and make some kind of schedule, the ICE will be worth every penny it costs you. David J.

it lets you debug in real-time. if you want to make your own hardware and debug software on it, it would be very useful. --emer On Sun, 29 Jul 2001, simha j wrote: > Hi all, > > I am new to DSP processor. > I need to work on ADSP-2188.
