All integer registers are 32 bit. However, many of them have 16-bit or 8-bit subregisters. ax Low 16 bits ofeax bx Low 16 bits ofebx cx Low 16 bits ofecx dx Low 16 bits ofedx si Low 16 bits ofesi di Low 16 bits ofedi ...
1) 0x1(IL_ONLY) It means that assembly’s code is IL_ONLY that is it is pure IL thus it can be compiled to either 32 bit or 64 bit 2) 0x2(32BIT_ONLY) means that assembly’s code must be compiled to 32 bit code and cannot be compiled to 64 bit. 3) 0x8 means assembly is...
The convention is to use "x64" to specify the group of processors that are both "32-bit" and "64-bit". x86 processor-based systems can run only 32-bit operating systems. x64 processor-based systems can run either 32-bit or 64-bit operating systems, and can execute all 32-bit x86 ...

Intel's 32-bit processors such as Pentium have 64-bit wide data bus and therefore fetch 8 bytes per access. Based on this, I'm assuming that the physical addresses that these processors emit on the address bus are always multiples of 8. Firstly, is this conclusion correct? Secondly, if...

The 64-bit cache is a firewall cache; this means the buffer size is rounded up to a multiple of PAGESIZE, and all buffers are allocated so that the end of the buffer is at the end of a page. The allocation is then done in such a way that there is an unmapped VA hole *after*...

64-bit. The beauty of the ARM design is the processor can seamlessly swap from one mode to the other during its normal execution. This means that the decoder for the 64-bit instructions is a new design that doesn’t need to maintain compatibility with the 32-bit era, yet the processor ...
