Using DMA in Lime’s 16-bit Host Interface Modes – DMA access is very important for large-volume, high-speed data transfer from the host CPU to the GDC (graphic display controller). One of the most common uses is displaying the Startup screen (a bitmap) in an automotive cluster or navigation application after the system powers up.

Memory Utilization and Data Traffic Pattern in Fujitsu Graphics Display Controller ICs – One of the important design considerations for using these GDCs is graphics memory utilization. This paper will examine the traffic pattern across the different interfaces in a typical Fujitsu GDC, then identify potential bottlenecks in the system. Finally, it will compare the dedicated and shared architectures for graphics memory, proposing a balanced approach between the two that also optimizes system performance, cost, and board space utilization.

Different Techniques for Bitmap Fading Using the MB86276 – Fujitsu’s Graphic Display Controller (GDC) product line is currently in its third generation. It consists ofthe high-end MB86297, the middle end MB86296, and the low-end MB86276. The first two have a PCI interface and the last one has an SRAM-type interface for the host controller. The MB86276’s low cost, small form factor, and relatively low power consumption are its most attractive features.

Telematic Applications for the Fujitsu MB86294 Graphics Display Controller: Connection with Intel PXA250 Processor – Graphic display controllers (GDCs) are an integral part of any graphic display system. They are used in both PC-based systems and embedded display systems. Fujitsu’s graphic display controllers have been designed specifically for embedded applications such as vehicle navigation systems.

Containing Sound and Light Wireless Video Coming Up Net Using MPEG-4 – Many of us over the age of 30 will remember Dick Tracy’s watch, the one from the 1950s that allowed the comic strip detective to make phone calls from his wrist. Sure, he had a limited number of people he could call, but anyone watching him do it was impressed.
