The present invention relates to a method for data transfer between a host and a device as well as to respective apparatus. A host is seen as a communication apparatus which organizes data traffic. A device is seen as dependent on the host. In a tiered-star topology there are usually multiple devices connected to one host. A method for data transfer between a host (H) and a device (D1, D2) through pipes (CTRL1, CTRL2, B_I1, B_I2, B_I3, B_O1, B_O2, B_O3) is presented. The available memory in the host (H) is divided into multiple segments (HMC1, HMC2, HMB1, HMB2, HMB3, HMB4). The assignment of segments (HMC1, HMC2, HMB1, HMB2, HMB3, HMB4) is changed between pipes (CTRL1, CTRL2, B_I1, B_I2, B_I3, B_O1, B_O2, B_O3) in dependence on the pipe traffic. |
