The Analog Devices Web Site http://content.analog.com/anom/anomprintdisplay/0,1828,58~1,00.html lists a DSPTools anomoly (DSP0230 ) for the 21xx/Compiler Anomaly: Compiler doesn't support arrays larger than 8192 elements Solution: Code generated by the compiler cannot access C arrays larger than 8192 elements, since the code will have a "MODIFY" instruction, which uses a 14-bit M register, to adjust the array index. Sure enough, writes to the last half of a 16K element array are incorrectly written as 0's. The listed solution doesn't help. Is there a solution (other than splitting the arrays)? In C? In Assembly? Where is the bit-size of the M register defines to be 14 bits? Regards! Don Waldron |
