CONFIG_COMP_FIR¶

FIR component

Type: bool

Help¶

Select for FIR component. FIR performance can differ between DSP
ISA and compiler used. FIR will perform best when MAC instructions
are available in ISA and are used by the compiler. i.e. xt-xcc on
xtensa will generate MAC instructions but GCC on xtensa won't.
Filter tap count can be severely restricted to reduce FIR cycles
and FIR performance for DSP/compilers with no MAC support

Direct dependencies¶

SOF

(Includes any dependencies from ifs and menus.)

Default¶

y
