  11. Filterkärnan FILTER: Process(Data2) is Type Data Is Array (0 To 6) of Integer Range -128 To 127; Variable w : Data; Variable s : Integer Range -8192 To 8191; Begin w := To_Integer(Data2) & w(0 To 5); s := 0; For l In b'Range Loop s := s + b(l)*w(l); End Loop; s :=s/32; pclk <= pclk + 1; If s > 127 Then Data1 <= "00111111"; Elsif s < -128 Then Data1 <= "10000000"; Else Data1 <= To_Signed(s,8); End If; End Process;
