Pipeline CAMAC Cont roller CAMAC reply frames CAMAC command frames Pipeline CAMAC Controller TX RX The controller gets a command frame from RX via CAMAC command FIFO, executes the frame in a 1 usec. and puts a reply frame to TX via CAMAC reply FIFO. The command frame and the reply frame contain CAMAC N, A, F, Status (Q,X) and 24-bit data. March 2003 Y.Yasu

PCI operat ion PCI operat ion Y.Yasu March 2003
PCI operat ion Programmed I/O : Generate CAMAC codes for CAMAC write/read/NDT; check whether TX FIFO is available; for(i=0;i<N;i++) { write data to TX data1/2 registers; } check whether RX FIFO is available; for(i=0;i<N;i++) { read data from RX data1/2 registers; } Extract CAMAC data and the status; March 2003 Y.Yasu
PCI operat ion (cont .) Block transfer : Generate CAMAC code for CAMAC write/read/NDT; check whether TX FIFO is available; start reading data with non-blocking; write data with blocking. wait for the completion interrupt of the read operation; Extract CAMAC data and the status; This algorithm makes CAMAC write and the read operate concurrently.
