# The DSP filters spend a lot of time spinning around in little
# loops multiplying and adding arrays of numbers. The Intel "SSE"
# instructions, introduced in 1999 with the Pentium III series,
# can speed this up considerably.
#
# SSE2 instructions, added in 2000, don't seem to offer any advantage.
#
#
# Let's take a look at the effect of the compile options.
#
#
# Times are elapsed time to process Track 2 of the TNC test CD.
#
# i.e. "./atest 02_Track_2.wav"
# Default demodulator type is new "E" added for version 1.2.

# ---------- x86 (32 bit) ----------

# gcc 4.6.3 running on Ubuntu 12.04.05.
# Intel(R) Celeron(R) CPU 2.53GHz. Appears to have only 32 bit instructions.
# Probably from around 2004 or 2005.
#
# When gcc is generating code for a 32 bit x86 target, it assumes the ancient
# i386 processor. This is good for portability but bad for performance.
#
# The code can run considerably faster by taking advantage of the SSE instructions
# available in the Pentium 3 or later.

#

# If you compile with the RPi 2 specific options above and try to run it on the RPi
# model B (pre version 2), it will die with "illegal instruction."

# You would expect "-march=native" to produce the fastest code.

#
# 1. In my benchmarks, above, it has a negligible impact if any at all.
# 2. Some older versions of gcc don't recognize "native" as a valid choice.
# 3. Results are less portable. Not a consideration if you are
# building only for your own use but very important for anyone
# redistributing a "binary" version.
#
# If you are planning to distribute the binary version to other
# people (in some ham radio software collection, RPM, or DEB package),
# avoid # fine tuning it for your particular computer. It could
# cause compatibility issues for those with older computers.
