Method for transmitting a datum from a time-dependent data storage means
View Patent ↗A method of transmitting a datum from a time-dependent data storage means, the datum being that most recently acquired before the occurrence of an allocated transmission slot; the method comprising the steps of: writing a first acquired datum to a first side of the data storage means; transferring the first datum to a second side of the data storage means; and writing a next datum, acquired before the occurrence of the next allocated transmission slot, to the first side of the data storage means; wherein the method further comprises the step of: replacing the first acquired datum in the second side of the data storage means with the next acquired datum; and transmitting the next acquired datum from the data storage means at the next allocated transmission slot.
1. A method of transmitting datum from a time-dependent data storage system, the method comprising the steps of:
transmitting a first datum from a first buffer of the time-dependent data storage system at an occurrence of a first allocated transmission slot;
writing a second datum to a second buffer of the time-dependent data storage system at the occurrence of the first allocated transmission slot;
transferring the second datum to the first buffer of the time-dependent data storage system before an occurrence of a second allocated transmission slot;
writing a third datum, acquired before the occurrence of the second allocated transmission slot, to the second buffer of the time-dependent data storage system;
replacing the second datum in the first buffer of the time-dependent data storage system with the third datum stored at the second buffer before the occurrence of the second allocated transmission slot; and
transmitting the third datum from the data storage system at the second allocated transmission slot.
2. The method as claimed in claim 1 , wherein the method is operated within a time division multiple access protocol.
3. The method as claimed in claim 1 , wherein the method is operated within the FlexRay (trademark) protocol.
4. A time-dependent data storage system comprising:
a logic unit; and
a double buffer in communication with the logic unit, the double buffer adapted to transmit a first datum from a transmit-side of the double buffer at an occurrence of a first allocated transmission slot, to write a second datum to the transmit-side of the double buffer whilst waiting for a second allocated transmission slot, and to write a third datum, subsequently acquired whilst waiting for the second transmission slot, to a host-side of the double buffer;
wherein the logic unit is adapted to transfer the second datum from the host-side to the transmit-side whilst waiting for the second allocated transmission slot, and the second datum is transmitted from the transmit-side upon the occurrence of the second allocated transmission slot.
5. The system of claim 4 wherein the system operates in accordance with a time division multiple access protocol.
6. The system of claim 4 wherein the system operates in accordance with the FlexRay (trademark) protocol.
7. The method as claimed in claim 2 , wherein the method is operated within the FlexRay (trademark) protocol.
8. The system of claim 5 wherein the system operates in accordance with the FlexRay (trademark) protocol.
9. A method comprising:
transmitting a first datum from a transmit-side of a double buffer at an occurrence of a first allocated transmission slot;
writing a next datum of a plurality of second datum to a host-side of the double buffer at the occurrence of the first allocated transmission slot;
transferring the next datum of the plurality of second datum from the host-side to the transmit-side before an occurrence of a second allocated transmission slot;
writing each datum of the plurality of second datum sequentially to the host-side of the double buffer before the occurrence of the second allocated transmission slot;
replacing a previously acquired datum of the plurality of second datum in the transmit-side with a most recently acquired datum of the plurality of second datum stored at the host-side before the occurrence of the second allocated transmission slot; and
transmitting the most recently acquired datum from the double buffer at the occurrence of the second allocated transmission slot.
10. The method as claimed in claim 9 , wherein the method is operated within a time division multiple access protocol.
11. The method as claimed in claim 10 , wherein the method is operated within the FlexRay (trademark) protocol.
12. The method as claimed in claim 9 , wherein the method is operated within the FlexRay (trademark) protocol.
13. The method of claim 9 , wherein a current datum in the transmit-side buffer is transmitted from the data storage system at an occurrence of each allocated transmission slot.
14. The method of claim 1 , wherein the time-dependent data storage system includes a double buffer.
15. The method of claim 14 , wherein the first buffer is a transmit-buffer of the double buffer.
16. The method of claim 14 , wherein the second buffer is a host-side buffer of the double buffer.
17. The method of claim 1 , wherein a current datum in the first buffer is transmitted from the data storage system at an occurrence of each allocated transmission slot.
18. The method of claim 1 , wherein each new datum written into the second buffer before the occurrence of each allocated transmission slot replaces a current datum written in the first buffer.
19. The system of claim 4 wherein a current datum in the transmit-side buffer is transmitted from the data storage system at an occurrence of each allocated transmission slot.
20. The system of claim 4 wherein each new datum written into the host-side buffer before the occurrence of each allocated transmission slot replaces a current datum written in the transmit-side buffer.
