  • Unlike in ADSP-214xx, you don't need to enable the FIR accelerator in PMCTL1 register explicitly in ADSP-SC58x/ADSP-2158x.


  • Unlike as in ADSP-214xx, the byte address of the input/output/coefficient buffers should be converted in to word address (by right shifting the byte address by 2 bits) for initializing the FIR index/base registers.
