Bin2ddr

A memory file used to convert an executable file to a DDR file

use to normal sim-ddr :

Convert generic binary files: ./bin2ddr -i xxx.bin -o ./out.dat -m "row,ba,col,bg"

./bin2ddr -i ckpt.zstd -o ./out.dat -m "row,ba,col,bg" -r gcpt.bin

use to fpga :

make FPGA=1

./bin2ddr -i ready-to-run/linux-xs.bin -o liunx.bin -m "row,ba,col,bg"

use to memh compression :

This function removes unused checkpoint memory by analyzing the program in the checkpoint

Use make nemu-update before use to update the nemu file used

example

./ready-to-run/riscv64-nemu-interpreter -b --restore ckpt.zstd -r gcpt.bin -I 40000000 --mem_use_record_file compress-out.txt

./bin2ddr -i ckpt.zstd -o ./out.dat -m "row,ba,col,bg" -r gcpt.bin -c compress-out.txt
