ADSP-21469 vs ADSP-2158x FFT Accelerator

Hello,

We are using 21469 fft accelerator in our design, coded in assembly and heavily relies on register and interrupts access. Looking to migrate to 2158x. From my understanding so far, there is an API provided for the accelerator on the 2158x and minimal register access, interrupts, etc. Please clarify/provide the following

1) Can we program the accelerator on 2158x in assembly, access all registers and setup interrupts to suit our needs like on the 21469

2) Comparison of the 21469 and 2158x accelerators

Thanks

Brian
