Assembly source

code:

fir_q31_q31_q31.asm

Code size and cycles: Size: 194 bytes

Instruction Cycles: 34 + NbOutput * (20 + 4 * FirNumberCoeffs)

Test:

Two test cases are provided. For each test case, two files allow to

test the function:

●

an input vector file (filterX_q31_q31_q31.in)

●

an output vector file (filterX_q31_q31_q31.res).

The configuration is the following:

●

number of coefficients: 32

●

number of output samples: 201

To perform the test, initialize the Delay line[] to zero, then Coeff[]

and Input[] with the filterX_q31_q31_q31.in file./ The first values

are the coefficients (lsb first) of the filter and the rest of the values

are the input values (lsb first). The output vector file contains the

result value (lsb first). (See the example for declarations).
