5.4 Memory
5.4.1
DRAM Memory
The Qui is equipped with 512 MB of dynamic RAM. Part of the DRAM is reserved for
the Windows operating system and is not accessible by user applications. The remaining
memory 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 memory 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 is not retained through a power cycle or reboot. The split
between program memory and storage memory can 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.
5.4.2
Changing the Memory Allocation
1. In the Control Panel, double-tap System. The System Properties dialog appears.
