DATA PROCESSING APPARATUS AND A METHOD OF SYNCHRONIZING A FIRST AND A SECOND PROCESSING MEANS IN A DATA PROCESSING APPARATUS

摘要

A data processing apparatus according to the invention comprising at least a first (1.2) and a second processing means (1.3). The first processing means being capable of providing data by writing tokens in a buffer means (2.1) which are readable by the second processing means for further processing. The processing means are assigned a first and a second synchronization counter. The first synchronization counter (writec) is modifiable by the first processing means (2.1)and is readable by the second processing means (1.3). The second synchronization counter (readc) is modifiable by the second processing means (1.3), and readable by the first processing means (1.2). The first synchronization counter (writec) is indicative for a number of tokens being written by the first processing means (1.2). The second synchronization counter (readc) is indicative for a number of tokens being read by the second processing means (1.3).
