h2. Demo Specifications

Specifications of the x86 (8086) instruction set architecture (ISA) can be found in "$MICROTESK_HOME/arch/demo/x86/model/x86.nml":http://forge.ispras.ru/projects/microtesk/repository/entry/trunk/microtesk/src/main/arch/demo/x86/model/x86.nml.

Each instruction is described in [[nML Language Reference|nML]] by means of the following constructs (_mov r16/r16_ is taken as an example):
14 8 Alexander Kamkin
15 10 Alexander Kamkin
## the signature
16 8 Alexander Kamkin
<pre>op mov_r1616 (dst: GPR16, src: GPR16)</pre>
17 10 Alexander Kamkin
## the assembly format
18 8 Alexander Kamkin
<pre>syntax = format("mov %s, %s", dst.syntax, src.syntax)</pre>
19 10 Alexander Kamkin
## the binary encoding
20 8 Alexander Kamkin
<pre>image = format("1000101111%s%s", dst.image, src.image)</pre>
21 14 Alexander Kamkin

34 32 Alexander Kamkin
Test templates for the x86 ISA can be found in "$MICROTESK_HOME/arch/demo/x86/templates":http://forge.ispras.ru/projects/microtesk/repository/entry/trunk/microtesk/src/main/arch/demo/x86/templates.

To run template processing use the following command:
46
<pre>$MICROTESK_HOME/bin/generate.sh x86 block.rb --code-file-prefix block --code-file-extension -v</pre>
47
When the processing is finished, files with the resulting assembly code can be found in @$MICROTESK_HOME@
