1. does 8-bit processor have to face endianness problem?    stackoverflow.com

If I have a int32 type integer in the 8-bit processor's memory, say, 8051, how could I identify the endianess of that integer? Is it compiler specific? I think this is ...

2. Memory leak in 32 bit CPU processor and no leak in 64 bit processor CPU    stackoverflow.com

I have a C code that runs without any memory leak in 64 bit CPU processor but shows leak in 32 bit processor. What can be the reason for it. GCC ...

3. Memory loss in following code when the CPU is 32 bit processor    stackoverflow.com

I have a function to convert integer to string .The function is

char * Int_String(int Number)
{
    char* result;
    NAT   size = 1;

4. Why do 64 bit systems have only a 48 bit address space?    stackoverflow.com

I an book i read the following:

The 32-bit processors have 2^32 possible addresses, while curent 64-bit processors have a 48-bit address space

5. Increasing performance of 32bit math on 16bit processor    stackoverflow.com

I am working on some firmware for an embedded device that uses a 16 bit PIC operating at 40 MIPS and programming in C. The system will control the position of ...

6. Can a 32-bit processor really address 2^32 memory locations?    stackoverflow.com

I feel this might be a weird/stupid question, but here goes... In the question Is NULL in C required/defined to be zero?, it has been established that the NULL pointer points ...

7. POD type sizes on a 64bit processor    bytes.com

They change because different processors have different size registers, i.e. it is a physical property of the processor. Some processors, notably the 64bit ones used in PCs today are equally happy using 32bit or 64bit values so then it becomes a property of how the operating system was compiled (in 32 or 64 bit mode)

8. How to find the bit width of a processor    bytes.com

Hello Friends, I wanted to know how to find out the bit width of a processor....whether it is 32bit or 64bit or 16 bit, can any one help how to write a c program for that...the code should be portable to any microprocessor or microcontroller bye... Hmm,word length of a processor changes size of a basic types as a integer.So by ...

9. Compiling error on 64 bit processor    cboard.cprogramming.com

Hi, I want to implement the raw ethernet program (Appendix B.) for my tests but the code only compiles (without warnigns or errors) on my old pentium 2 laptop that has no network card and run on Redhat 9 kernel 2.2.14. I did "gcc -c util.c", "gcc -c client.c" then "gcc -o client util.o client.o". But when I run the first ...
