The Amstrad CPC (short for "Colour Personal Computer") is a series of 8-bit home computers produced by Amstrad between 1984 and 1990. It was designed to compete in the mid-1980s home computer market dominated by the Commodore 64 and the ZX Spectrum; it successfully established itself primarily in the United Kingdom, France, Spain, and the German-speaking parts of Europe.
The TMS9918 chip which uses a proprietary 15-color YUV composite video palette encoded palette [34] plus a transparent color, intended to be used by the hardware sprites and simple video overlay. When used as an ordinary background color, it is rendered using the same color as the screen border.
Hardware varies in the number of sprites supported, the size and colors of each sprite, and special effects such as scaling or reporting pixel-precise overlap. Hardware composition of sprites occurs as each scan line is prepared for the video output device, such as a cathode-ray tube , without involvement of the main CPU and without the need ...
Covers three facets of the sprite support hardware the system used. Each number in the table cell is preceded by two letters. S# For the first facet, is the total number of hardware sprites the system could support, in hardware (not counting re-use of the same hardware). if the system doesn't support hardware sprites at all the table cell only ...
The Amstrad CPC character set (alternatively known as the BASIC graphics character set) [1] is the character set used in the Amstrad CPC series of 8-bit personal computers when running BASIC (the default mode, until it boots into CP/M). This character set existed in the built-in "lower" ROM chip.
The C64 hardware sprites use _exactly the same_ memory as emulated sprites, its just taken by the video processor rather than the program. And they work in any mode. The CPC has flyback registers like the C64 yes, but because of the different speed at which colour moves they don't work very well. 120.20.235.251 ( talk ) 13:45, 3 February 2019 ...
Amstrad was known for cheap hi-fi products but had not broken into the home computer market until the CPC 464. [1] Their consumer electronic sales were starting to plateau and owner and founder Alan Sugar stated "We needed to move on and find another sector or product to bring us back to profit growth". [ 4 ]
VDCs often had special hardware for the creation of "sprites", a function that in more modern VDP chips is done with the "Bit Blitter" using the "Bit blit" function. One example of a typical video display processor is the "VDP2 32-bit background and scroll plane video display processor" of the Sega Saturn.
