TS-7250 MANUAL
INTRODUCTION
The
TS-7250
's user can power up the board and immediately begin application
development. Of course, should you wish to configure your own version of Linux or use a
different operating system, this is easy too. Technologic Systems provides the solution to
fast application development without tedious OS configuration.
Impressive Performance
The ARM920T's 32-bit architecture, with a five-stage pipeline, delivers very impressive
performance at very low power. The EP9302 CPU has a 16 KB instruction cache and a 16
KB data cache to provide zero-cycle latency to the current program and data, or they can
be locked to guarantee no-latency access to critical sections of instructions and data. For
applications with instruction-memory size restrictions, the ARM920T’s compressed Thumb
instruction set can be used to provide higher code density and lower Flash storage
requirements.
As a benchmark, the
TS-7250
's CPU integer performance, at a supplied 200 MHz, is
about twice as fast as the Technologic Systems 133MHz 586-based products.
