Abstract
The data processing device according to the invention comprises a first processing unit (1) linked to a first bus (5), a second processing unit (2) linked to a second bus (6), a first bus master (3) linked to the first bus (5), a second bus master (4) linked to the second bus (6), a first and a second communication channel (7, 20, 8, 21) linking the first and the second bus master (3, 4) with each other, and a control unit (9) controlling the data transfer between the first and the second bus master (3, 4) via the first and the second communication channel (7, 20, 8, 21).
Claims18
A data processing device, comprising:
- a first processing unit (1) linked to a first bus (5), a second processing unit (2) linked to a second bus (6), a first bus master (3) linked to said first bus (5), a second bus master (4) linked to said second bus (6), a first and a second communication channel (7, 20, 8, 21) linking said first and said second bus master (3, 4) with each other, and a control unit (9) controlling the data transfer between said first and said second bus master (3, 4) via said first and said second communication channel (7, 20, 8, 21).
A method for transferring data from a first memory of a first processor system to a second memory of a second processor system, comprising the following steps:
- said first memory transmits said data via a first bus (5) to a first pipeline (8) with the help of a first bus master (3) with a first clock rate, and said data are transferred from the first pipeline (8) with the help of a second bus master (4) with a second clock rate via a second bus (6) to said second memory.
