SHARC 21489 Sleep / Stand-by Mode

I am using the ADSP-21489 for my thesis.


Is it possible to set the Core into a sleep mode and wake it up again?

For energy saving reasons.


I use the SPORT continuously with DMA and pingpong chaining, it receives data from the ADC.

When one of the buffers is full, I process the received data.

Processing is fast (6ms), so I have a lot of time left (150ms) to set the core into sleep mode.


I cant find it in the data sheet and I am sure my professor will ask this


Best regards
