Abstract
The present invention relates to a data processing system based on a multithreaded operating system. The data processing system comprises at least one processor (PROC) for processing data based on multiple threads, at least one controller unit (CU) for controlling the communication between said at least one processor (PROC) and an external peripheral device (PD) connected to said at least one controller unit (CU). Said at least one controller unit (CU) comprises at least one buffer memory (BM) for buffering data from said peripheral device (PD) connected to said at least one controller unit (CU), and at least one memory managing unit (MMU) for managing the access to said at least one buffer memory (BM) by mapping said at least one buffer memory (BM) into N banks (C-C) each with a dedicated prefetch register (Addr.-Addr.). At least one of said multiple threads (T-T) is mapped to one of said N banks (C-C) and its dedicated prefetch register (Addr.-Addr.).
