IA32 Assembly Number Mystery
assembly,bit-manipulation,ia-32
From point #2: x & x = 0 if and only if x = 0, so (2 * a) & a = 0. Since multiplying by 2 is a single bit shift, we can see that this is true for any number that doesn't have two set bits next to...
IA-32 assembly: Effect of 8 bit operations on 32 bit registers
Normally the suffix is ignored/not important if proper register names are given. So the instruction above is a 32 Bit instruction because esi and ecx are 32 Bit registers.
Why is the adressspace increased from 32 to 36 bits with PAE
paging,computer-architecture,ia-32,page-tables
The physical address space can be 36 bits. The linear address space is always 32 bits in IA-32. Its achieved by increasing the size of the page directory pointer table entries, page directory entries and page table entries. They are all 64 bits with PAE paging enabled.And actually with PAE...
In IA-32 assembly language, can IDTR, GDTR or LDTR be modified or 'loaded' without the LIDT, LGDT and LLDT instructions?
The IDTR, GDTR or LDTR can be modified by: LIDT, LGDT and LLDT instructions entering system management mode, modifying the values in the "state save" area, then leaving system management mode to cause the modified values to be loaded using hardware virtualisation extensions, where host is able to modify the...
How to install ia32-libs in Ubuntu 14.04 LTS (Trusty Tahr)
You can try this to install the 32-bit library (not all in ia32-libs): apt-get install program:i386 Or if you want to install the whole ia32-lib instead, try the following order: sudo -i cd /etc/apt/sources.list.d echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list apt-get update apt-get install ia32-libs PS: In...
