In the history of video games, the fourth generation of video game consoles, more commonly referred to as the 16-bit era, began on October 30, 1987, with the Japanese release of NEC Home Electronics' PC Engine (known as the TurboGrafx-16 in North America).
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.
Load Q instruction: converts 8-bit or 16-bit, signed or unsigned integers to SP floating point; Store Q instruction: converts SP floating point to 8-bit or 16-bit, signed or unsigned integer; Branch Prediction Unit (BPU) Load-Store Unit (LSU) System Register Unit (SRU) Memory Management Unit (MMU) Branch Target Instruction Cache (BTIC)
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). [5]
The Atari ST series has a digital-to-analog converter of 3-bits, eight levels per RGB channel, featuring a 9-bit RGB palette (512 colors).Depending on the (proprietary) monitor type attached, it displays one of the 320×200, 16-colors and 640×200, 4-colors modes with the color monitor, or the high resolution 640×400 black and white mode with the monochrome monitor.
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.
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]
