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.
