Question:
Does ADI compiler use instructions involving the anomaly such as BITEXP and BITRET for ADSP-214xx?
Answer:
Our Compiler, Libraries and SSL\DD do not make use of BITEXP and BITRET functions.
The BITEXT and BITDEP instructions aren’t related to the normal bit access instructions.
They're for the bit FIFO, which is new to 214xx. Please refer page no: 3-27 of the SHARC programming reference linked below for more details:
