I've read several sheets of the manual and also examples on using the IMDW bits but finally I didn't come to a satisfying answer.
To be sure I do not miss anything I'd like to raise this question here.
I do algorithms in blocks, each block gets input and output buffers in internal memory.
So I do a 40-Bit accurate floating point calculation with the F0-F15/SF0-SF15 registers and I want to keep that 40-Bit result for the next algorithm block. At the moment my memory is normal word with 32-Bit (simplifies also the SIMD issue with 40-Bit, but that can be solved).
I've tried an example from the EZ:
i0=data1;m0=0; px2=0x12345678; px1=0x9A000000; r1=px;
USTAT1 = dm(SYSCTL); bit set USTAT1 IMDW2; dm(SYSCTL) = USTAT1;
Block 2 is defined as 48-Bit wide "seg_pmda" area.
Using the simulator the memory shows me left aligned 0x123456789A00, r0 shows me 0x56789A0000.
That is not what I expected.
Can someone help me here?
