For example, to support a paravirtualized frame buffer
on Linux, a Linux front-end driver would write the buffer of the frame it got from user space into a shared memory area; it would then signal the hypervisor using hypervisor calls to output the frame via a back-end driver.
-- NVIDIA Quadro FX 1500 -- Provides high performance coupled with two dual-link DVI connectors, 256MB GDDR3 frame buffer
memory and HD video output
Features include resolution of 1344 x 1024 pixel, 12-bit dynamic range, exposure time of 5 [micro]s to 1 hr, and internal frame buffer
for continuous image capture (64-MB min).
A frame buffer
is released if buffer for its predecessor frame has already been released.
Liquid chrome 5.6 also features a real-time frame buffer
for video output from Pinnacle Commotion Pro, Adobe After Effects and Discreet combustion, as well as ASIO drivers for no-latency audio output from Pinnacle Steinberg Nuendo.
The MiMagic 6 includes 1.7 megabits of internal SRAM for video and graphics frame buffer
; dedicated hardware for pre-processing of camera input; a 2D BitBLT graphics engine to improve performance of Graphical User Interfaces; dual video overlay datapaths, and numerous input/output (I/O) devices such as UARTs, USB, and memory card controllers.
Key features of the new controller include a 64-bit 2D graphics accelerator, embedded memory for LCD frame buffer
, and flexible CPU interface.
The VS2000 feature set includes a 60 MHz 32-bit Lightfoot RISC CPU core, 10/100 Ethernet MAC with a 4KB frame buffer
SRAM, external memory controller with 32MB addressing range, configurable 8- or 32-bit external memory bus, glueless interface including four individually-programmed chip selects, two cache controllers, two UARTS, three SPI ports, watchdog timer, real-time clock and interrupt controller.
The DP83016's 256Kbytes on-chip frame buffer
and memory allocation algorithm provides the most optimum solution without the need for any external memory.
CyberALADDiN-T brings significant cost savings to the notebook PCs by eliminating the need for an external frame buffer
and taking full advantage of the Shared Memory Architecture (SMA).
The unit boasts a chip speed of 83 MHz, a 2 MB SDRAM frame buffer
, a power consumption of only 0.3 W, and supports for a variety of SXGA, SGA, SVGA and VGA LCD displays.
Typically, an array of memory, called a frame buffer
, is used to store information such as color and opacity for each pixel or voxel.
