Description
Zoran’s COACH 6 is the sixth Camera On A CHip (COACH) digital
camera processor.
The COACH 6 digital camera processor combines excellent image
quality & feature set with an extremely aggressive camera bill of
materials.
COACH 6 is offered in two versions: COACH 6e (ZR36440), support-
ing up to 3 Megapixel sensors, and COACH 6p, (ZR36442) support-
ing up to 16 Megapixel sensors. For the camera developer, both ver-
sions have identical interface sets and development kit. The two ver-
sions provide cost effectiveness across the entry level and mid-range
digital camera market segments.
The COACH 6 includes all required hardware and firmware to sup-
port multiple-field interlaced CCD sensors and CMOS sensors. In
addition to CompactFlash, Secure Digital and SmartMedia, COACH 6
expands the Flash card support to XD and to Memory Stick.
COACH 6 integrates a speech audio CODEC and a Real Time Clock
system. It offers direct interface to View-LCD display, eliminating the
need for an LCD controller IC. COACH 6 eliminates the need for an
external microcontroller. Internal A/D converters, PWM engines and
additional general-purpose IO pins were added in order to directly
control Zoom and Auto Focus lenses. COACH 6 emphasizes image
quality with true 12-bit enhanced sensor processing and hardware
based image enlargement, which allows for smooth, zero-delay digi-
tal zoom across all camera operational modes.
In an effort to ease programming complexity and allow for third party
software development, the COACH 6 is powered by a 32bit RISC
CPU and a standard operating system. USB 1.1 point-to-point master
and an enhanced serial port complement the new software architec-
ture. With these improvements, COACH 6 is optimally positioned to
expand digital camera connectivity possibilities beyond the PC.
Camera control software layer (created by COACH customers) is
compatible with the COACH 5. This enables an easy migration from
the COACH 5 to the COACH 6.
The COACH 6 comes with a complete development package that
includes a "manufacture-ready" CamMini™ reference design, a com-
prehensive set of software development tools, and WHQL approved
PC drivers.
