Questions tagged [16-bit]

Referring to computer architecture with addresses and other data units 16 bits wide.

In computer architecture, 16-bit integers, memory addresses, or other data units are those that are at most 16 bits (2 octets) wide. Also, 16-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.

Why is there no 2-byte float and does an implementation already exist?

Assuming I am really pressed for memory and want a smaller range (similar to short vs int). Shader languages already support half for a floating-point type with half the precision (not just convert back and forth for the value to be between -1 and…

Define 16 bit integer in C

I need to declare an integer in the size of 16 bit, in C. I know that short and int sizes are machine dependent. I tried to use "stdint.h", but it seems that they simply do typedef short int16_t So my question is: Am I missing something and short…

How to use high and low bytes?

I am trying to represent 32768 using 2 bytes. For the high byte, do I use the same values as the low byte and it will interpret them differently or do I put the actual values? So would I put something like 32678 0 or 256 0? Or neither of those?…

How did 16-bit C compilers work?

C's memory model, with its use of pointer arithmetic and all, seems to model flat address space. 16-bit computers used segmented memory access. How did 16-bit C compilers deal with this issue and simulate a flat address space from the perspective…

Converting Win16 C code to Win32

In general, what needs to be done to convert a 16 bit Windows program to Win32? I'm sure I'm not the only person to inherit a codebase and be stunned to find 16-bit code lurking in the corners. The code in question is C.

C# bitwise shift on ushort (UInt16)

I need to perform a bitwise left shift on a 16-bit integer (ushort / UInt16), but the bitwise operators in C# seem to apply to int (32-bit) only. How can I use << on an ushort, or at least get to the same result with a simple workaround?
