20 /* This file supports the zy1000 debugger: http://www.zylin.com/zy1000.html
22 * The zy1000 is a standalone debugger that has a web interface and
23 * requires no drivers on the developer host as all communication
24 * is via TCP/IP. The zy1000 gets it performance(~400-700kBytes/s
25 * DCC downloads @ 16MHz target) as it has an FPGA to hardware
26 * accelerate the JTAG commands, while offering *very* low latency
27 * between OpenOCD and the FPGA registers.
29 * The disadvantage of the zy1000 is that it has a feeble CPU compared to
30 * a PC(ca. 50-500 DMIPS depending on how one counts it), whereas a PC
31 * is on the order of 10000 DMIPS(i.e. at a factor of 20-200).
33 * The zy1000 revc hardware is using an Altera Nios CPU, whereas the
34 * revb is using ARM7 + Xilinx.
36 * See Zylin web pages or contact Zylin for more information.
38 * The reason this code is in OpenOCD rather than OpenOCD linked with the
39 * ZY1000 code is that OpenOCD is the long road towards getting
40 * libopenocd into place. libopenocd will support both low performance,
41 * low latency systems(embedded) and high performance high latency
