Block Diagram
Low-cost devices usually are equipped with low speed processors and limited
memories. In reality, they have neither the capability nor practicality to manage
complicated network TCP/IP protocols. The ARM Cortex™-M3 32-bit processor
has been specifically developed to provide a high-performance, low-cost platform
for a broad range of applications including microcontrollers, automotive body
systems, and industrial control systems, networking by converting data stream
between network TCP/IP and popular serial port signals.
Instead of processing TCP/IP packets directly, devices need only deal with those
interface signals, which greatly simplifies the complexity of TCP/IP network in
linkage. The ARM Cortex-M3 processor provides outstanding computational
performance and exceptional system response to interrupt while meeting low cost
requirements through small core footprint, industry leading code density enabling
smaller memories, reducing pin count, and low power consumption.
The central core of ARM Cortex-M3 processor, based on a 3-stage pipeline
Harvard bus architecture, incorporates advanced features including single cycle
