Description
The PC8265A PowerQUICC II
is a versatile communications processor that inte-
grates on one chip, a high-performance PowerPC (PC603e) RISC microprocessor, a
highly flexible system integration unit, and many communications peripheral control-
lers that can be used in a variety of applications, particularly in communications and
networking systems.
The core is an embedded variant of the PC603e microprocessor, specifically referred
to later in this document as the EC603e, with 16 Kbytes of instruction cache and
16 Kbytes of data cache and floating-point unit (FPU). The system interface unit (SIU)
consists of a flexible memory controller that interfaces to almost any user-defined
memory system, a 60x-to-PCI bus bridge and many other peripherals, making this
device a complete system on a chip.
The communications processor module (CPM) includes all the peripherals found in
the PC860, with the addition of three high-performance communication channels that
support new emerging protocols (for example, 155-Mbps ATM and Fast Ethernet).
Equipped with dedicated hardware, the PC8265A can handle up to 256 full-duplex,
time-division, multiplexed logical channels.
