Joern Moe writes ] In the falcon they use sync ] mode on a 16 bit bus. This gives a 4 clock cycle for each longword ] access to the bus. This implies a 25% reduction in performance, not 50%. That is wrong. Synchrone cycles on the 68030 (i.e. those terminated by STERM rather than DSACK) must be 32-bit wide. Refer to the 030 User s Manual. There is no other way than DSACK to end a 16-bit wide exchange. Vincent. -- In memoria di mori di Furiani.
