On a 64-bit machine is the size of an int in Java 32 bits or 64 bits?

See the....
It's one of the Java language features that the size of the integer does not vary with the underlying computer .
So, the same program will require more memory on a 64 bit JVM32 bits.
Of object references, from 32 bits to 64.

In gcc, i want to do a 128 bits xor with 2 C variables, via asm code: how?
asm ( "movdqa %1, %%xmm1;" "movdqa %0, %%xmm0;" "pxor %%xmm1,%%xmm0;" "movdqa %%xmm0, %0;" :"=x"(buff) /* output operand */ :"x"(bu), "x"(buff) :"%xmm0","%xmm1" );
but i have a...

Each of those declares a properly-aligned 128 bit value */ print128(a); print128(b); print128(x); }
compile with (gcc, ubuntu 32 bit)
gcc -msse2 -o app 00ff00ff00ff00ff
In the code above....
Alignment by using the __m128 or __m128i data types.

I'm trying to code a simple, sufficiently accurate filter for validating a piece of hardware in an RTL simulation. We're simulating the randomness inherent in a chip's flip-flops, by randomly initializing all the flip-flops in the design to either 0 or...

Be as simple as multiplying the probabilites;
For 1 bit it is 50%
For 2 bits it is 50%^2 = 25%
For 3 bits that accepts bit patterns of the correct type, and then simulate the pattern for each number of bits is about....

I am beginning to port a program which is written in C and have several pieces of code written in assembly with instructions for a 32 bit machine - like ljmp - to a 64 bits machine.
Is there a place/document that have the instructions, in assembly, for...

No bits, they're ****ing disgusting.
No bits, I hate them in orange juice.

I have a 16 bit value with its bits "interlaced".
I want to get an array of 8 items (values 0 to 3) that stores the bits in this order:
item 0: bits 7 and 15 item 1: bits 6 and 14 item 2: bits 5 and 13 ... item 7: bits 0 and 8 This is a trivial solution...

The addition of slide moves the relevant bits adjacent to each other to treat the low and high order bits symmetrically, with interleaved 0's, shift them off from each other.
Is in reusing the shifted value.

The cast is pretty great I think.
Yeah, from what I know there are some blindsides this season, not as many as say Amazon or PI but some people are definitely surprised, more than the last few seasons at least .

8 bits representing the number 7 look like this:

Three bits are set. What is the best algorithm to determine the number of set bits in a 32-bit integer?

Get a live 64 CD and try to boot on your system, if it could not then
it is 32 bits.
Me how to define is my system 64 bits or 32 bits?

Hello quick question regarding bit shifting
I have a value in HEX = new byte[] { 0x56, 0xAF };
which is 0101 0110 1010 1111
i want to the first n bits, example 12
then shift off the remaining 4 (16-12) to get 0000 0101 0110 1010 (1386 dec)
i cant wrap...

You can use a BitArray and then easily copy each bit to the right, starting from the right.
