FIR II Data Type

[hockey_goalie_01]

With regards to the FIR II Compiler in the Quartus IP, does the 'Signed Binary' input and output type truly refer to signed binary (sign and magnitude) or to two's complement?

For clarity:

In signed binary, -1 would be represented as 10000001.

In two's complement, -1 would be represented as 11111111.

Thanks

Hi,

You can refer to the following link section 3.4.1.

"The FIR II IP core supports two’s complement, signed fractional binary notation, which allows you to monitor which bits the IP core preserves and which bits it removes during filtering"
