SuperGrafx
The , also known as simply the SuperGrafx, is a fourth-generation home video game console manufactured by NEC Home Electronics and released in Japan in 1989. It is the successor system to the PC Engine, released two years prior. Originally known as the PC Engine 2 during production stages, it was purported as a true 16-bit home console, featuring improved graphics and audio capabilities over its predecessor. The console was rushed to market, released several months before its initial intended release date in 1990, only having modest updates to the hardware. With only six retail games released that took advantage of the console's hardware updates, the SuperGrafx was a commercial failure, selling only 75,000 units total. None of the hardware advancements it possessed were carried over to later PC Engine models, such as the Duo. Hardware Compared to the PC Engine, the SuperGrafx has four times the amount of working RAM for the main CPU. Its main upgrade is an additional video ch ...

Fourth Generation Of Video Game Consoles
In the history of video games, the fourth generation of 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). Though NEC released the first console of this era, sales were mostly dominated by the rivalry between Sega and Nintendo across most markets: the Sega Mega Drive (''Sega Genesis'' in North America) and the Super Nintendo Entertainment System (SNES; ''Super Famicom'' in Japan). Cartridge-based Handheld game console, handheld consoles became prominent during this time, such as the Game Boy, Nintendo Game Boy (1989), Atari Lynx (1989), Game Gear, Sega Game Gear (1990) and TurboExpress (1990). Nintendo was able to capitalize on its success in the previous, third generation, and managed to win the largest worldwide market share in the fourth generation as well. Sega, however, was extremely successful in this generation and began a new fran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hudson Soft HuC6270
HuC6270 is a video display controller (VDC) developed by Hudson Soft and manufactured for Hudson Soft by Seiko Epson. The VDC was used in the PC Engine game console produced by NEC Corporation, and the upgraded PC Engine SuperGrafx. Besides use in consoles, the VDC was used in two arcade games. The arcade version of ''Bloody Wolf , released in Europe as ''Battle Rangers'', is a run and gun arcade game released by Data East in 1988. Two commandos take on an entire army with many weapons, and defeat bosses to advance levels. Plot Snake and Eagle, two commandos of the Blo ...'' ran on a custom version of the PC Engine. The arcade hardware is missing the second 16-bit graphic chip known as the video color encoder that is in the PC Engine. This means the VDC directly accesses palette RAM and builds out the display signals/timing. A rare Capcom quiz-type arcade game also ran on a modified version of the SuperGrafx hardware, which used two VDCs. References {{DEFAULTSORT:Hudson ...

Home Video Game Console
A home video game console is a video game console that is designed to be connected to a display device, such as a television, and an external power source as to play video games. Home consoles are generally less powerful and customizable than personal computers, designed to have advanced graphics abilities but limited memory and storage space to keep the units affordable. While initial consoles were dedicated units with only a few games fixed into the electronic circuits of the system, most consoles since support the use of swappable game media, either through game cartridges, optical discs, or through digital distribution to internal storage. There have been numerous home video game consoles since the first commercial unit, the Magnavox Odyssey in 1972. Historically these consoles have been grouped into generations lasting each about six years based on common technical specifications. As of 2021, there have been nine console generations, with the current leading manufactures ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hudson Soft HuC6280
The HuC6280 8-bit microprocessor is Japanese company Hudson Soft's improved version of the WDC 65C02 CPU, an upgraded CMOS version of the popular NMOS-based MOS Technology 6502 8-bit CPU manufactured for Hudson by Seiko Epson and NEC. The most notable product using the HuC6280 is NEC's TurboGrafx-16 video game console. Description The HuC6280 contains a 65C02 core which has several additional instructions and a few internal peripheral functions such as an interrupt controller, a memory management unit, a timer, an 8-bit parallel I/O port, and a programmable sound generator (PSG). The processor operates at two speeds, 1.79 MHz and 7.16 MHz. A slightly revised HuC6280A was released and used in the PC Engine CoreGrafx and SuperGrafx. This revision reportedly fixed some minor audio issues in those systems. Memory mapping The HuC6280 has a 64 KB logical address space, but a 2 MB physical address space. The HuC6280 uses a Memory Management Unit that splits the memory spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HuCard
The is a ROM cartridge in the form of a card, designed by Hudson Soft for NEC's PC Engine and PC Engine SuperGrafx video game consoles, which were originally released in 1987 and 1989, respectively. In the United States, where the PC Engine was marketed as the TurboGrafx-16, the HuCard is alternately called the TurboChip. The HuCard is an evolution from an earlier Hudson Soft technology, the Bee Card, which it developed in the early 1980s as a distribution medium for MSX computer software. The Bee Card is an EEPROM device that is slightly thinner than the HuCard. It has 32 connectors whereas the HuCard has 38. Most video game cartridges have a large plastic housing to protect the PCB while providing enough space inside for radiant heat and, less often, a button cell. The PCB in a HuCard or Bee Card is protected by a rigid, glossy polymer that conducts heat; since the PC Engine and TurboGrafx-16 leave one side of the card partially exposed while inserted in the console, heat dis ...

Triangle Wave
A triangular wave or triangle wave is a non-sinusoidal waveform named for its triangular shape. It is a periodic, piecewise linear, continuous real function. Like a square wave, the triangle wave contains only odd harmonics. However, the higher harmonics roll-off, roll off much faster than in a square wave (proportional to the inverse square of the harmonic number as opposed to just the inverse). Definitions Definition A triangle wave of period ''p'' that spans the range [0,1] is defined as: x(t)= 2 \left, \frac - \left \lfloor \frac + \frac \right \rfloor \ where \lfloor\,\ \rfloor is the Floor and ceiling functions, floor function. This can be seen to be the absolute value of a shifted sawtooth wave. For a triangle wave spanning the range the expression becomes: x(t)= 2 \left , 2 \left ( \frac - \left \lfloor + \right \rfloor \right) \right , - 1. A more general equation for a triangle wave with amplitude a and period p using the modulo operation and absol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palette (computing)
In computer graphics, a palette is the set of available colors from which an image can be made. In some systems, the palette is fixed by the hardware design, and in others it is dynamic, typically implemented via a color lookup table (CLUT), a correspondence table in which selected colors from a certain color space's color reproduction range are assigned an index, by which they can be referenced. By referencing the colors via an index, which takes less information than needed to describe the actual colors in the color space, this technique aims to reduce data usage, including processing, transfer bandwidth, RAM usage, and storage. Images in which colors are indicated by references to a CLUT are called indexed color images. Description As of 2019, the most common image colorspace in graphics cards is the RGB color model with 8 bits per pixel color depth. Using this technique, 8 bits per pixel are used to describe the luminance level in each of the RGB channels, therefore 24 b ...

Sawtooth Wave
The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform. It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle. A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform. The convention is that a sawtooth wave ramps upward and then sharply drops. In a reverse (or inverse) sawtooth wave, the wave ramps downward and then sharply rises. It can also be considered the extreme case of an asymmetric triangle wave. The equivalent piecewise linear functions x(t) = t - \lfloor t \rfloor x(t) = t \bmod 1 based on the floor function of time ''t'' is an example of a sawtooth wave with period 1. A more general form, in the range −1 to 1, and with period ''p'', is 2\left( - \left\lfloor + \right\rfloor\right) This sawtooth function has the same phase as the sine function. While a square wave is constructed from only odd harmonics, a sawtooth wave's sound is harsh and clear and its spectrum contai ...
