MPLAB supports MPLAB ICD 2 as an on chip debugger for PICmicros with flash 
memory and dsPIC devices.

ack.

[Silicon LabsC8051F family, LPC900 80C51 variants, uCPSD34xx]

but ist this "on-chip debug" like Motorola BDM, where you can access
memory (variables...) during program execution without affecting the
target (using CPU time)?

For example, the LPC2000 supports "realtime access" AFAIS with an
interrupt routine which makes it unusable for me because I have
several extremly time critical applications.

That's the reason why I love Motorola (Freescale) BDM - I can look at
the state of my target without affecting it. Invaluable!
