Intel 2700G


Intel 2700G is a low power and MVED1 technology.

Different variants

This accelerator comes in 3 variants: The 2700G3, 2700G5 and 2700G7.

2700G3

The 2700G3 is the value version of the accelerator. It has 384 kB of on-die memory suitable for driving an HVGA or smaller graphics display.

2700G5

The 2700G5 is the performance version of the accelerator. It has 704 kB of on-die memory suitable for driving a VGA resolution display and decoding MPEG-4 video.

2700G7

The 2700G7 is the same as the 2700G5 but is stacked with 16 MB of local memory with a 100 MHz, 32-bit bus in the same package.

Features

All the chips have a 75 MHz, 32-bit core shipped in BGA packaging.

Accelerated dual display

The 2700G has its own LCD controller and two LCD outputs. This allows for the XScale processor and 2700G's graphics displays to be used at the same time. The 2700G can drive an external display up to 1024×768 or 1280×1024.

2D graphics acceleration

The accelerator supports clipping, alpha blending and anti-aliasing. It also has a variety of block level transfer functions. The 2D accelerator is capable of up to an 84 million pixels per second fill rate.

3D graphics acceleration

The 2700G has a complete hardware rendering pipeline and is compatible with the OpenGL ES 1.0 standard, using the common-lite profile. It features texture compression, anisotropic filtering, and per vertex fogging among other things. The 3D accelerator is capable of processing about 831 000 triangles per second.

Video acceleration

The 2700G performs Inverse Zig-Zag, Inverse Discrete Cosine Transform, and Motion Compensation to speed up MPEG-1, MPEG-2, MPEG-4 and WMV video decoding. The accelerator can decode MPEG-1, 2 and WMV at 720×480 and MPEG-4 at 640×480, both at over 30 frames per second.

Devices

The 2700G was featured in the Dell Axim X50v, Dell Axim X51v, Gigabyte GSmart t600, Pepper Pad 2 and Palm Foleo.
It was also used in some standalone signage kiosks such as the MediaStaff DS and HID's, such as the Clipsal DALIcontrol DCLCD70 LCD Touch Screen Controller, and the Advantech UbiQ-350 and UbiQ-470.
As of Intel selling its XScale unit to Marvell, this device is discontinued.
