1.4 EP93xx Processor Highlights

1.4.1 High-Performance ARM920T Core

The EP93xx Processors feature an advanced ARM920T Core design with an MMU that
®
supports Linux
ARM920T's 32-bit microcontroller architecture, with a five-stage pipeline, delivers impressive
performance at very low power. The included 16 KByte instruction cache and 16 KByte data
cache provide zero-cycle latency to the current program and data, or can be locked to
provide guaranteed no-latency access to critical instructions and data. For applications with
instruction memory size restrictions, the ARM920T's compressed Thumb
provides a space-efficient design that maximizes external instruction memory usage.
1.4.2 MaverickCrunch
The EP9302, EP9307, EP9312, and EP9315 processors include an advanced
MaverickCrunch co-processor that provides mixed-mode math functions to greatly accelerate
the floating-point processing capabilities of the ARM920T Core. The MaverickCrunch co-
