Remove outTimetmp and reuse inFreqTmp #166

Closed howard0su closed 3 years ago

howard0su commented 3 years ago

Reduce the pressure on cache by reuse the buffer.

ik1xpv commented 3 years ago

It is a little bit faster than v1.1.0.
I made test on I7-3770 I tested 64M adc clock , USB 12k audio LO to frequency not exact bin multiplier to activate shift Both are compiled in release. IF sample rate 32M 16M 8M 4M 2M this branch#68fc88a CPU%15 10 8 8 7 ver 1.1.0 CPU% 16 12 10 9 8 - -

How about 128m sample rate with 64m bandwidth?

I made this test with HDSDR Beta5 to be able to manage the 64M SR I7-3770 with128M adc clock , USB 12k audio LO to frequency not exact bin multiplier to activate shift IF sample rate 64M 32M 16M 8M 4M 2M this branch#68fc88a CPU % 26 16 13 12 11 10 ver 1.1.0 CPU% 27 17 13 12 11 10

The two versions are very close as CPU load. This branch is a little (0.5% ?? ) better on my I7-3770

thank you so much. This sounds good. I will merge this.
