1.1.4
J-Link ARM Pro
J-Link Pro is a JTAG emulator designed for ARM cores. It is fully
compatible to J-Link and connects via Ethernet/USB to a PC
running Microsoft Windows 2000, Windows XP, Windows 2003
or Windows Vista. Additional support for Cortex-R4 and Cortex-
R8 cores will be available in the near future. J-Link Pro comes
with licenses for all J-Link related SEGGER software products
which allows using J-Link Pro "out-of-the-box".

1.1.4.2 Download speed
The following table lists performance values (Kbytes/s) for writing to memory (RAM):
Hardware
Rev. 1 via USB
Rev. 1 via TCP/IP
Table 1.3: Download speed differences between hardware revisions
All tests have been performed in the testing environment which is described on Mea-
suring download speed on page 188.
The actual speed depends on various factors, such as JTAG/SWD, clock speed, host
CPU core etc.
