/*

/* Project: 		HSO/PACS, SPU HLSW

/* User Manual issue:   3.1

/* Date:		04-04-2003

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



SPU HLSW 3.1 is positioned as an upgrade of SPU HLSW 3.0, containing the following 



new features:

 

  - Remove the Link SMCS Reset before to Start the Link Connection

  - Add the possibility to Copy data from RAM to EEPROM via Command

  - Upgrade the Transmission of the TM Packets in Buffer Transmission Mode to be compatible with

    SPU HLSW data transmission design

  - Bug in DMC Header handling is corrected

  - Add the SMCS Chip Reset After the Jump to HLSW command



These will be explained in the specific sections that follow.





The SPU HLSW Development Team.





Remove the Link SMCS Reset before to Start the Link Connection

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

This Link reset was done each time before SPU HLSW is starting the DPU link as slave. It was done after an SMCS chip reset.

The Link reset after an SMCS chip reset has no effect on the connection. 



Add the possibility to Copy data from RAM to EEPROM via Command

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

For the Update of a new HLSW in the SPU EEPROM, no additional Upload of the HLSW TC packets

is needed. Because the HLSW could copy itself to EEPROM using this command.



Upgrade the Transmission of the TM Packets in Buffer Transmission Mode

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

The previous philosophy of the Buffer Transmission Mode is to send the TM Packets at fixed

interval of 60ms to reach a TM rate of 260Kbits/s. To avoid the TM packets loss, whenever DPU is not ready to receive 

Packets within 60 ms, SPU HLSW is sending 74 TM packets at time intervl of 4440 ms



Bug in DMC Header handling is corrected

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

Buffered DMC Data in the SPU was not cleaned after detecting a DMC Header error (Invalid Data Type).

This may cause a corrupted compressed entity, the one following the DMC Header error.

This buffer is actually cleaned in the SPU HLSW



Add the SMCS Chip Reset After the Jump to HLSW command

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

An SMCS chip reset after the jump to ASW is added in the HLSW. This provides a clean transition

between the SUSW and the HLSW.
