The arithmetic logic unit (ALU) was 16-bit wide and could add two 16-bit internal registers in 2.4 microseconds, and memory to register adds of 16-bit numbers in 3.2 microseconds. [ 7 ] Like the PDP-11, the CP1600 used eight 16-bit "general purpose" processor registers , although they were not truly general-purpose as in modern designs.
16-bit audio, 32 kHz sampling rate; Optional Dolby Surround support; Stereo audio with: 4 FM synthesis channels/voices; 3 square wave channels/voices; 1 white noise generator; 6 ADPCM channels (12-bit) @ 18.5 kHz sampling rate [74] 1 ADPCM channel (16-bit) @ 1.8 to 55.5 kHz sampling rate [74]
The advantage over 8-bit or 16-bit integers is that the increased dynamic range allows for more detail to be preserved in highlights and shadows for images, and avoids gamma correction. The advantage over 32-bit single-precision floating point is that it requires half the storage and bandwidth (at the expense of precision and range).
All calculations are performed to 24 bit accuracy; Texture mapping color mode: [11] Mode 4: 4-bit CLUT (16 colors) Mode 8: 8-bit CLUT (256 colors) Mode 15: 15-bit direct (32,768 colors) Mode 24: 24-bit (16,777,216 colors) Sprite engine [citation needed] 1024×512 framebuffer, 8×8 and 16×16 sprite sizes, bitmap objects [citation needed]
A common example is the Data General Nova, which was a 16-bit design that performed 16-bit math as a series of four 4-bit operations. 4-bits was the word size of a widely available single-chip ALU and thus allowed for inexpensive implementation. Using the definition being applied to the 68000, the Nova would be a 4-bit computer, or 4/16.
For example, a standard RGB 8-bit image can only show 256 values of grey and hence only 256 heights. By using colors, a greater number of heights can be stored (for a 24-bit image, 256 3 = 16,777,216 heights can be represented (256 4 = 4,294,967,296 if the alpha channel is also used)). This technique is especially useful where height varies ...
Four registers are used to refer to four segments on the 16-bit x86 segmented memory architecture. DS (data segment), CS (code segment), SS (stack segment), and ES (extra segment). Another 16-bit register can act as an offset into a given segment, and so a logical address on this platform is written segment:offset, typically in hexadecimal ...
