Hitachi LSI HD63484 Advanced CRT Controller chip (ACRTC) is a GPU created by Hitachi in 1984 that supports 4K display resolution. [1]
The LSI HD63484 was built in 2 μm CMOS technology and had about 60,000 MOSFETs and could operate at 8 MHz. ACRTC introduced a screen resolution of 4096×4096 pixels at 1-bit color depth (monochrome), or 1024×1024 at 16-bit color (65,536 colors). Focused on computer graphics for the emerging desktop publishing market with bitmap printing. [2] The chip had the ability to program the synchronization signal of CRT monitors. It could support up to 2 megabytes of video memory and offered an asynchronous DMA bus interface that could be mapped to 16-bit ISA and VME buses.
