From an ultra powerful processor through to software development
The NBS5xxx circuit board is based on an ARM 9 processor with very large scale integration: "a circuit board
in a chip". It contains a series of smart peripherals and a
32-bit RISC
processor rated at 180 MHz, capable of
remaining active with very low consumption levels.
These manage:
•
Software
actual isolation
, essential in a multi-application context. The design of the processor
ensures the integrity of the software applications and their data. Thus no application can have its
data or code consulted or altered by another.
•
Simultaneity
among the various peripherals, reducing the transaction time required, for example,
when printing while inputting data on the keypad.
