[Tremor] Tremor lowmem on TI 55x DSP

[EXTERN Wacker Klaus (Extern; CM-DI/ESP1)]

I try to port Tremor lowmem on TI 55x DSP. 
I am not familiar with the 54x and actually I just started to work with
the 55x.
But here is a short summery 

55x							54x
2 16bit MAC						1 17bit MAC
3 data read busses					2 data read
busses 
2 data write busses
32 KW (64KB) DRAM					?
64 KW (128KB) SRAM					?
Better DMA
Can only address words(2 bytes, can you believe this)	?
Fast SDRAM interface					?
Instruction cache					?

The ALUs seemed to be similar
Because of only three read data busses (stupid ) the two MACs have to
share one parameter (or it is a constant which is in register)
Therefore the two MACs do not produce the double amount of MAC
operations

Thanks for the help
Klaus
