/*-----------------------------------------------------



SPU HLSW 11.0 is positioned as an upgrade of SPU HLSW 10.1, containing the following new features:



* CPU Workload improvement for spectroscopy.

* CPU Workload and compression efficiency improvement in photometry, based on the test pattern mode.

* Improve the DMC header error visibility in the SPU HK.



This will be explained in the specific sections that follow.



The required Decompression SW version is:

- Decompress11 (Ground Decompression Software in Java)



The SPU HLSW Development Team.



CPU Workload improvement for spectroscopy

------------------------------------------

The arithmetic encoding algorithm has been removed from the chain for lossless spectroscopy data compression. This decreases the lossless compression processing time by about 10 -33% for spectroscopy data.



CPU Workload and compression efficiency improvement in photometry

------------------------------------------------------------------

Averaging algorithm has been speed up in this version by a new restructuration of the mean algorithm with glitch detection.

Furthermore, a faster RZIP algorithm is used with range 3-3-7. According to a new sorting this RZIP range presents less processing time  and better compression ratio than that with range 7-6-4 used in HLSW version 10.1. This was tested for test pattern data.



Improve the DMC header error visibility in the SPU HK

------------------------------------------------------

Several error codes is included in this new version of the software to signal the different DMC header errors while compression is started.



The following c/h files has been changed since HLSW version 10.0:

- average.c

- buf_spec.c

- buf_bol.c

- csw.c

- genspu.h

- Hk.c

- llc.c- ramp_ft.c

- supervs.c- T_S_Red.c
