Hi ,


From the datasheet of ADSP-21489, I got to know that SIMD has two processing elements, and in my program SIMD is enabled.


But in MODE1 register PEYEN bit is '0'. I thought to enable this by setting this bit to '1' , so that simd is enabled always, but if I do that my program is hanging in case of fileops.


Is it a correct way to use that bit?\


And if simd based dsp functions is used, then this bit will be set automatically and de-asserted back ??
