Application note
Optimized memory copy routine for TCP/IP on the STR91x
Introduction
This application note describes an optimized memory copy for TCP/IP. It can also be used
for any memory copy.
This routine is written in ARM assembler, and can be called by any C program which
conforms to the ARM procedure call standard.
Using this optimized routine will accelerate the memory copy up to 20 times as compared to
a standard implementation.
This optimized buffer alignment routine has been integrated in the HAL Ethernet driver
distributed by ST.
This program has been fully tested and run inside a TCP/IP stack. However,
STMicroelectronics cannot guarantee that this driver is flawless in all applications.
