Experiments with cpu emulator

To build, first install vade : https://github.com/nsauzede/ns_vade

To test, first get some BIOS, eg:

myem$ wget -q -O bios.bin https://github.com/640-KB/GLaBIOS/releases/download/v0.1.6/GLABIOS_0.1.6_091322_8088.ROM

Then :

myem$ vade clean test
    RM  pkg
    RM  bin
    CXX bus.o
    AR  bus.a
    AR  libbus.a
    CXX cpu.o
    AR  cpu.a
    AR  libcpu.a
    CXX mem.o
    AR  mem.a
    AR  libmem.a
    CXX myem.o
    AR  myem.a
    AR  libmyem.a
    CXX myem_test.o
    CC  testing.o
    AR  myem_test.a
    AR  libmyem_test.a
    CXX myem_test.exe
    RUN ./bin/myem_test.exe
