low. Their core and bus architecture offer high
performance processing optimized for managing
intensive data exchanges between different types of
communication protocols. It capitalizes on the available
development infrastructure of current Power
Architecture® devices and will be supported with
software drivers and an operating system to assist with
users implementations.
The PXN20 devices have two levels of memory
hierarchy, a 32 KB unified cache, and 2 MB of internal
flash. The PXN20 has 592 KB on-chip L2 SRAM and
