Description

The EP9315 is a highly integrated system-on-chip processor that paves
the way for next-generation consumer and industrial electronic products.
The EP9315 features an advanced 200 MHz ARM920T processor design with a
memory management unit (MMU) that supports Linux Windows CE and many
other embedded operating systems. The ARM920T's 32-bit microcontroller
architecture, with a five-stage pipeline, delivers impressive
performance at very low power. Designers of digital media servers,
jukeboxes, telematic control systems, thin clients, set-top boxes,
point-of-sale terminals, industrial controls, biometric security systems
and GPS devices will benefit from the EP9315's integrated architecture
and advanced features. In fact, with its broad range of peripheral
interfaces, the EP9315 is suited to even more applications. By enabling
or disabling the EP9315's peripheral interfaces, designers can also
reduce development costs and accelerate time to market by creating a
single platform that can be modified to deliver differentiated end
products. Cirrus Logic's embedded processor products are complemented by
a range of complete operating systems. Both Microsoft Windows CE.NET and
Linux solutions are available with total driver support.
