4.14.1 Standalone Configuration
Standalone configuration offers the most simple and inexpensive system solution for generic
LCD monitors. In this configuration the OCM executes firmware stored internally in
gm5110/20. This is illustrated in Figure 23A. The on-chip firmware provides all the standard
functions required in a high-quality generic LCD monitor. This includes mode-detection,
auto-configuration and a high-quality standard OSD menu system. No external ROM is
required (which reduces BOM cost) and no firmware development effort is required (which
reduces time-to-market).
In Standalone configuration many customization parameters are stored in NVRAM. These
include the LCD panel timing parameters (including TCON programming), the color scheme
and logos used in the OSD menus, the functions provided by the OSD menus, and arbitrary
firmware modifications. These customization parameters are described in the Standalone
User’s Guide (B0108-SUG-01). Based on the customization parameters, G-Wizard (a GUI-
based development tool used to program Genesis devices) produces the hex image file for
NVRAM. G-Probe is then used to download the NVRAM image file into the NVRAM
device. This is illustrated in Figure 24 below.
