PowerQUICC II^™
Description
The PC8260 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 no 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 (available in future revisions) 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 PC8260 can handle up to 256 full-duplex,
time-division, multiplexed logical channels.
