DRAM Memory
The QuickPanel View/Control is equipped with 64 MB of dynamic RAM. Part
of the DRAM (16 MB) is reserved for the Windows CE operating system and
is not accessible by user applications. The other 48 MB is split between two
functions: an object store for temporary file storage, and the main memory
for running programs.
Typically, compressed programs stored in FLASH are expanded and moved
to DRAM for execution. Temporary storage of program variables or data
files is also provided by DRAM
—any data stored in DRAM will not be
retained through a power cycle or reboot.
The split between program memory and storage memory may be adjusted
as necessary to make more room for one or the other, depending on your
specific application needs. For example, if you find that an application is
short of memory, use the System Properties dialog box to alter DRAM
memory allocation.
Caution
Setting Program Memory too low may prevent additional
applications from starting, or may cause currently running
applications to fail due to lack of memory. Setting Storage
Memory too low may prevent the saving of files into the
object store portion of the file system, which may also cause
application failures.
