Abstract
A data transmission device is used to forward data that have been received from a first device, and are intended for a second device, to the second device. The data transmission device described has a whole series of characteristics that allow the data that are to be transmitted to be transmitted very easily very quickly and which confer additional functions on the data transmission device.
Claims48
A data transmission assembly for forwarding data received from a first device, and intended for a second device, to the second device, the first device being part of a module containing the data transmission assembly, the data transmission assembly comprising:
- a data transmission device transmitting to the second device not only the data to be forwarded to the second device but also information about a place to which the data to be forwarded need to be transmitted within the second device, said data transmission device ascertaining the information about the place to which the data to be forwarded need to be transmitted within the second device from an address used to address said data transmission device when the data to be forwarded were supplied to said data transmission device.
A data transmission assembly for forwarding data received from a first device, and intended for a second device, to the second device, the first device being part of a module containing the data transmission assembly, the data transmission assembly comprising:
- a data transmission device transmitting to the second device not only the data to be forwarded to the second device but also information about a place to which the data to be forwarded need to be transmitted within the second device, the information about the place to which the data to be forwarded need to be transmitted within the second device contains a number of an address range and an address offset specifying a particular address within the address range.
A data transmission assembly for forwarding data received from a first device, and intended for a second device, to the second device, the data transmission assembly comprising:
- a data transmission device having an address prediction device for predicting an address or a portion of the address to which the data to be forwarded need to be transmitted within the second device.
A data transmission assembly for forwarding data received from a first device, and intended for a second device, to the second device, the data transmission assembly comprising:
- a transmission device transmitting to the second device not only the data to be forwarded to the second device but also information about a place to which the data to be forwarded need to be transmitted within the second device, said data transmission device checking whether it is possible to assume that the second device is able to ascertain the place to which the data to be forwarded need to be transmitted within the second device when the second device is sent no information or less information about the place in question, and, if this is the case, said data transmission device transmitting to the second device no information or less information about the place to which the data to be forwarded need to be transmitted within the second device.
A data transmission assembly for forwarding data received from a first device, and intended for a second device, to the second device, the first device sending the data transmission assembly not only the data to be forwarded but also information about a place to which the data to be forwarded need to be transmitted within the second device, the data transmission assembly comprising:
- a data transmission device, if the first device sends said data transmission device no information or less information about the place to which the data to be forwarded need to be transmitted within the second device, said data transmission device ascertaining the place using the information which is available in said data transmission device.
A data transmission assembly for forwarding data received from a first device, and intended for a second device, to the second device, the data transmission assembly comprising:
- a data transmission device producing an interrupt request signal when prompted by one of the first device and the second device.
A method for transmitting data, which comprises the steps of:
- providing a data transmission device;
- choosing addresses used for addressing the data transmission device when data to be forwarded are transmitted from the first device to the data transmission device such that the addresses completely or partially match addresses used to address other components of a module containing the data transmission device;
- receiving, in the data transmission device, the data from the first device, and the data being intended for a second device, and
- forwarding the data to the second device.
A data transmission assembly for forwarding data received from a first device, and intended for a second device, to the second device, the second device being part of a module containing the data transmission assembly, the data transmission assembly comprising:
- a data transmission device able to become a bus master on a bus connecting said data transmission device and the second device to one another, and said data transmission device forwarding the data to be forwarded via the bus to the second device at its own behest.
The data transmission assembly according to 36, wherein the module containing said data transmission device is a program-controlled unit.
