Question:
What is the difference between ADSP-SC58x and ADSP-214xx processors while using run time library functions which access data from external memory?
Answer:
In ADSP-SC58x processors,all data passed to the FFT functions cfftf, ifftf, and rfftf_2 (which uses SIMD function) must be allocated in internal memory.
But ADSP-214xx processors do support SIMD access to external memory, but not long word (LW) access to external memory.
