Original provenience: DSPstone benchmark suite (floating point),
|
||||
http://www.ice.rwth-aachen.de/research/tools-projects/entry/detail/dspstone
|
||||
|
||||
2015-10-10:
|
||||
- Removed original header comment, replaced by TACLeBench header.
|
||||
- Removed all preprocessor macros, integrated them directly in the source code.
|
||||
- Added prefix "iir" to all global symbols.
|
||||
- Added explicit forward declarations of functions.
|
||||
- Replaced local variables "wi", "coefficients" and "x" that store the
|
||||
benchmark's input data by global variables.
|
||||
- Replaced initialization function iir_pin_down by TACLeBench-compliant
|
||||
initialization code.
|
||||
- Removed second call of iir_pin_down from function iir_main since it does
|
||||
not make sense at all.
|
||||
- Added new function iir_return producing a checksum as return value.
|
||||
- Added new function iir_main according to TACLeBench guidelines.
|
||||
iir_main is annotated as entry-point for timing analysis.
|
||||
- Applied code formatting according to the following rules
|
||||
- Lines shall not be wider than 80 characters; whenever possible, appropriate
|
||||
line breaks shall be inserted to keep lines below 80 characters
|
||||
- Indentation is done using whitespaces only, no tabs. Code is indented by
|
||||
two whitespaces
|
||||
- Two empty lines are put between any two functions
|
||||
- In non-empty lists or index expressions, opening '(' and '[' are followed by
|
||||
one whitespace, closing ')' and ']' are preceded by one whitespace
|
||||
- In comma- or colon-separated argument lists, one whitespace is put after
|
||||
each comma/colon
|
||||
- Names of functions and global variables all start with a benchmark-specific
|
||||
prefix (here: bs_) followed by lowercase letter (e.g., bs_square)
|
||||
- For pointer types, one whitespace is put before the '*'
|
||||
- Operators within expressions shall be preceded and followed by one
|
||||
whitespace
|
||||
- Code of then- and else-parts of if-then-else statements shall be put in
|
||||
separate lines, not in the same lines as the if-condition or the keyword
|
||||
"else"
|
||||
- Opening braces '{' denoting the beginning of code for some if-else or loop
|
||||
body shall be put at the end of the same line where the keywords "if",
|
||||
"else", "for", "while" etc. occur

This program is part of the TACLeBench benchmark suite.
|
||||
Version V 2.0
|
||||
|
||||
Name: iir
|
||||
|
||||
Author: Juan Martinez Velarde
|
||||
|
||||
Function:
|
||||
The equations of each biquad section filter are:
|
||||
w(n) = x(n) - ai1*w(n-1) - ai2*w(n-2)
|
||||
y(n) = b0*w(n) + bi1*w(n-1) + bi2*w(n-2)
|
||||
|
||||
Biquads are sequentally positioned. Input sample for biquad i is
|
||||
xi-1(n). Output sample for biquad i is xi(n).
|
||||
System input sample is x0(n). System output sample is xN(n) = y(n)
|
||||
for N biquads.
|
||||
|
||||
Each section performs following filtering (biquad i) :
|
||||
|
||||
wi(n)
|
||||
xi-1(n) ---(-)---------->-|->---bi0---(+)-------> xi(n)
|
||||
A | A
|
||||
| |1/z| |
|
||||
| | wi(n-1) |
|
||||
| v |
|
||||
|-<--ai1----<-|->---bi1-->-|
|
||||
| | |
|
||||
| |1/z| |
|
||||
| | wi(n-2) |
|
||||
| v |
|
||||
|-<--ai2----<--->---bi2-->-|
|
||||
|
||||
The values wi(n-1) and wi(n-2) are stored in wi1 and wi2
