SUBJECT:                             CMAG source files

 

Short Description

 

This directory contains the source code for the 19-bit CMAG code as described in two upcoming papers. The directory contains the C-source code as well as the generated NOF tables. The following four tables are posted:

 

Mul/Add only 19-bit table: nof19l0.dat

MAG essential 19-bit table: nof19l1.dat

CSD table in 19-bit: nof19l2.dat

ALL 235 graphs 19-bit: nof19l5.dat

 

Each line of these files contains the following 12 entries:

 

costs       non-output fundamental sum (NOFS)        1-10 NOF values.

 

Use the optimal part of the RAG-n algorithm to generate the complete graph!

Use the magstat1.c program to compute the adder statistic in each tables.

 

If you like to generate the table yourself use the following steps:

1) Generate a CSD NOF table using the program:  csdnof1.c

2) Generate the code for all CMAGs using the work list wl19b05.dat and the program: magcg1.c The work list is sorted by the computation time. The generated program for all 235 CMAGs should look as the code:  magwl.c

3) Run the CMAG computation using the program maggwl1.c that uses the same work list and the include file magwl.c generated in step 2.

 

Hint for PC user: Open the files with WordPad and store to get correct CR/LF.
