dsk6713 power measurement

Hi Mottaz,

The information you need is located on the Spectrum Digital Website for the DSK6713: http://c6000.spectrumdigital.com/dsk6713/

Read the DSK6713 Technical Reference Rev. B and Schematics:

There are three power test points on the DSK at JP1, JP2 and JP4. All I/O current passes through JP2 while all core current passes through JP1. All system current passes through JP4. Normally these jumpers are closed. To measure the current passing through remove the jumpers and connect the pins with a current measuring device such as a multimeter or current probe.

JP1 - Measure current supplied to DSP Core - Core Voltage should be 1.26V

JP2 - Measure current supplied to I/O & all other chips - I/O voltage should be 3.3V

JP4 - Measure current supplied to voltage regulator (which powers the whole board) - Input voltage should be 5V

Hope this helps,

Mark

If you take a look at the DSK6713 Technical Reference Manual and schematics available on Spectrum Digital's support website (the manufacturer of the board), you will find JP1 and and JP2 provide access points to measure the current to just the DSP.

JP1 allows you to measure the current to the core power rail and JP2 allows you to measure the current to the I/O power rail of the C6713.

The tools you would need are a Digital Multimeter that can measure current.  Ideally, 2 of them so you can make measurements at the same time while running a particular application on the DSP.
