Understand mini_core design

[roman012285]

• [x] run example.c and examine the main function and how mini_core performs it
• [x] Examine the trackers inside the target/mini_core directory
• [x] use the following [line] (https://fpga-mafia.github.io/fpga_mafia_wiki/docs/rvc/intro)
• [x] add custom instruction add_inc for example add_inc x1, x2, x3 => x1 = x1 + x2 + 1 use inline assembly //asm(".word 0xf4f757a3" : /* outputs / : / inputs / : / clobbers */);
• [x] check the functionality of the instruction using the right tackers

./build.py -dut mini_core -test example -app - compile compile.c test ./build.py -dut mini_core -test example -app -hw -sim - compile the design (-hw flag) + simulate and elaboration (-sim flag)

Hi Roman,

here is the line of code we added to the exampl.c file:

Here is the code in binary and the log of the registers:

How you prove that it works, I dont see it from the tracker.

here i opened the tracker file in two windows the line is 17c and we can see that prior to the reg x16 was zero after it has 0xf+0xa+1 = 0x1a
