169020010 Channel Recovery Module Soft/Firmware Archive

This disk has all archive information relating to EEPROMs U42 and U43 used on
the CRM (1600020010), part of the JIVE MkIV Station Unit (1650020500)

Files crmx.U42 and crmx.U43 respectively are used to programme
U42 and U43

Directories:

CRM41xx - MicroController firmware

6010010a - Clock generation gate array design
6110010a - Multiplex modes gate array design
6210010a - Validity bit extraction gate array design
6310010a - Cross track parity gate array design
6410010a - De-multiplex modes gate array design
CRMARRAY - Generation of data for gate array include files

Each gate array design ends with the generation of a bit stream file 'design'.bit.
The individual bit files are combined in the correct sequence by the MAKEPROM utility
in the XILINX design environment in directory CRMARRAY.  This produces a configuration
file which can be converted to the correct format for insertion into an include file
for the firmware.

MAKEPROM generates CRMMMUX.MCS from 6010010a.bit, 6110010a.bit, 6210010a.bit,
6310010a.bit.  The order of the files is mandatory. Run the batch file 
S CRMMMUX to generate CRMMMUX.P to convert the data for the include file.

MAKEPROM generates CRMDMUX.MCS from 6010010a.bit, 6410010a.bit, 6210010a.bit,
6310010a.bit.  The order of the files is mandatory. Run the batch file 
S CRMDMUX to generate CRMDMUX.P to convert the data for the include file.

Note that the .fpf file contains the directives to convert the MCS file to a
form suitable for compiling into the microprocessor firmware.  However the file
type needs to be changed and additional comment information added as below.

The include files, which at this stage are CRMMMUX.P and CRMDMUX.P, need to be
incorporated to .h files for building into the microprocessor firmware.  This
may be done with any suitable ascii text editor.  An existing .h file can be
modified so that the new content overwrites the previous content.  The banner
in the .h file can be modified to identify the new gate array.  


To generate a new set of firmware using the new xilinx configuration ( assuming
a PC environment set up with the compiler etc.) have the new include files on
a floppy disk in drive a: and enter NEWROMS.  The NEWROMS batch file will
call make to build the firmware, then call splitrom via makeprom.bat to convert
hex file to 2 files one for each eeprom to program.
