To write or read a byte of video memory, the CPU first has to write two bytes on the VDP's control port to the VDC's internal address register. Next, the CPU performs the actual write or read on the VDP's data port. As a data byte is written or read, the TMS9918 automatically increments the internal address register.
A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to understand ...
The EIA/CEA-861-E standard has the first 64 short video descriptors above. It is used by HDMI 1.4–1.4b. The CTA-861-F standard has the first 107 short video descriptors above. It is used by HDMI 2.0–2.0b. The CTA-861-G standard has the full list of 154 (1–127, 193–219) short video descriptors above. It is used by HDMI 2.1.
The execution times listed in this table are based on an oscillator frequency of 270 kHz. The data sheet indicates that for a resistor of 91 kΩ at V CC =5 V the oscillator can vary between 190 kHz and 350 kHz resulting in wait times of 52.6 μs and 28.6 μs instead of 37 μs. If a display with the recommended 91 kΩ resistor is powered from 3. ...
Memory cards without encryption can be used to store PlayStation game saves, but PlayStation games would be unable to read from or write to the card – such a card could only be used as a backup. There are a variety of non-Sony manufactured memory cards available for the PlayStation 2, allowing for a larger memory capacity than the standard 8 MB.
To start a read transaction, the initiator has to provide on the Read address channel: the start address on ARADDR; the burst type, either FIXED, INCR or WRAP, on ARBURST (if present) the burst length on ARLEN (if present). Additionally, the other auxiliary signals, if present, are used to define more specific transfers.
Motorola 6845 CRT controller. The Motorola 6845, or MC6845, is a display controller that was widely used in 8-bit computers during the 1980s. [1] [2] Originally intended for designs based on the Motorola 6800 CPU and given a related part number, it was more widely used alongside various other processors, and was most commonly found in machines based on the Zilog Z80 and MOS 6502.
The DisplayPort AUX channel is a half-duplex (bidirectional) data channel used for miscellaneous additional data beyond video and audio, such as EDID (I 2 C) or CEC commands. [8]: §2.4 This bidirectional data channel is required, since the video lane signals are unidirectional from source to display. AUX signals are transmitted across a ...
