how mpc860 directly links with 1394bus chip(tsb12lv01)?

[zzasia]

where can  i  buy  a  chip like mpc106(named "bridge"),that is with  1394 bus  intead of PCI bus,...or  how  can i   realize   a  1394 bus  directly  with 60x  ,i  dislike  the   "PPC-PCI-1394OHCI PCI adapter-1394bus" mode.it is not fast and direct enough.

Looking to tsb12lv01 chip datasheet, I see this chip has memory-type interface to the host, so it may be connected directly to MPC860 memory controller, no specific bridge chip is necessary.

how to realize DMA(tsb12lv01 to memory), if take  tsb12lv01  as  memory.  In C language,veriaty locates in memory .  if  tsb12lv01 recieved  a block of several Mbyte ,(tsb12lv01 only has 2kbyte of  FIFO),,   so  must  move (or copy&paste) to memory  for mpc860 to process.       use  cpld  to control DMA?  or  use mpc860 to do  it?

MPC860 processor has DMA functionality, no external FPGA is necessary.

Please look MPC860 User Manual, Section 19.3 for detailed description.
