Help on selection of DSP for Medical

[amalfi]

medical dsp

Hi people,

I am a newcomer in the DSP design and I would appreciate if you could help me on this:
I have to select a DSP for a medical application. I will process 2 channels of ECG and combine them with data from a pulse oximeter.
I will perform many filters and to process the signals in the time and frequency domain. I guess I will need around 80 MIPs to be safe.
At the same time, I need:
+To control a 320x240 graphic display => Memory!!
+3 serial interfaces(2xUART+1xSPI)
+Small size , not-BGA DSP
+Code Protection
+ADCs
+Low power consumption
+If external memory is used, then how could I protect my code?

Besides, What graphical solution do you recommend me? Library or IC?
I was thinking on using a SoC with a graphical interface, but I do not know if it would be expensive or too slow for this application.

Thanks in advance

Amalfi
