Layers
Fujitsu GDCs feature a layered display structure providing six
to eight separate frame buffer layers. Each layer is capable of
managing unique content that can be rendered, captured from
one or more video sources, blitted from a bitmap library, or a
combination of these options. These functions are carried out in
the display controller block where the processing has little or no
impact on the GPU, which might be simultaneously processing
the rendering. At least four of the layers have separate color pal-
ettes, which are set up to draw using 8-bit pallet registers. Each
layer is independent, so some layers can be configured for pal-
letized color while others can be set for 16-bit-per-pixel direct-
color mode. Layers can have a uniform transparency setting with
a range of 256 levels. At least one layer will provide pixel-level
transparency settings to produce special effects such as a roving
spotlight on a navigation map.
In addition to the layer alpha settings, an alpha mask option can
be applied to bitmaps and fonts alike. When the mask is applied
to a font or bitmap, both are blitted to a layer in one simple
step. The effect is one of edge smoothing or anti-aliasing as
the edges of the source bitmap or font are blended to the layer
or layers below. When the alpha mask is combined with RGB
with alpha, layer level and pixel-level alpha, the possibilities for
special effects increase significantly.
Video Capture
The ITU-656 or RGB-format video-capture port displays the im-
ages from perimeter cameras as well as accepts and displays
video content. Because the GDC is a graphics processor, the
captured content can be handled as a texture and then mapped
to polygons for special effects, such as with Fujitsu’s 360-degree
Wrap-Around Video Image Technology. That technology maps
the images captured from four cameras onto a circular polygon
mesh to display a virtual, full-surround image.
Unique Features
As described earlier, Fujitsu GDC products are unique in that they
incorporate a GPU and an equally powerful display controller
that gives users a high degree of flexibility in how graphics are
processed and displayed. Fujitsu also incorporates many special
features designed specifically for high reliability applications. For
example, the Fujitsu Signature Unit (SU) is a special hardware
function designed to add a level of safety to certain applications.
Occasionally, incorrect memory reads or writes can result in im-
ages being shifted or put in the wrong place. The SU will perform
a checksum on specific critical content to ensure the images are
displayed in the right place. This eliminates the possibility, for
example, that a warning light would be hidden behind other
graphics or placed completely out of view.
SOC Versus Standalone GDCs
There are two basic categories of Fujitsu GDCs: stand-alone and
System on Chip (SoC). Historically, Fujitsu has first developed a
stand-alone GDC and then integrated the core into a SoC. The
benefit of the stand-alone architecture relates primarily to mem-
ory bandwidth. In SoCs, the internal processor and GDC share the
single external memory bus. Stand-alone GDCs have their own
dedicated memory and are not limited by other internal bottle-
necks characteristic of SoC designs. However, as process geom-
etries shrink and circuit-switching speeds improve, the internal
bandwidth limitations of SoC design are being neutralized when
compared with multi-chip stand-alone options.
GDC Families0
Fujitsu currently has five GDC families, each of which can feature
up to three variations.
MB88F332 “Indigo” Series: This sprite-based, non-rendering
GDC includes many peripheral-support functions such as
backlight control, an advanced sound generator, and six
stepper motor controls. The MB88F332 “Indigo” features on-
chip memory in the form of 160KB of NOR Flash and 128 KB
of SRAM. The MB88F332 “Indigo” device supports up to 512
bitmaps, making it capable of acting as a stand-alone GDC in
applications that require only animated bitmaps. The recently
released MB88F333 “Indigo-L” device is a lower cost addition to
the series. It supports two stepper motors and is packaged in a
smaller 176 LQFP package.
The MB88F33x “Indigo” Series can also be configured to work
with an advanced controller such as Fujitsu’s MB86R02 “Jade-D.”
This pseudo master/slave configuration is possible owing to the
inclusion of APIX, the high-speed serial interface that supports
both bi-directional communications. The two-chip setup enables
a broader variety of configurations that can reduce costs.
MB91590 “Sapphire”: This SOC device is based on Fujitsu’s
high-performance FR81S CPU core (which offers the highest per-
formance level in the industry). MB91590 “Sapphire” integrates
a version of the MB88F332 “Indigo” sprite core and external
video-capture capabilities, including both analog (NTSC/PAL)
and digital (RGB and BT656) support. An on-chip video memory
makes MB91590 “Sapphire” a fully self-contained, single-chip
solution for applications that require robust color display and
video-input capabilities. The device is particularly well-suited
for use in automotive instrument clusters and center consoles
