ABSTRACT:
A system for processing a stream of data and automatically selecting a portion or all of the data stream for block writing to a memory. The memory is capable of storing data in response to a block write command and a normal write command. The system contains a first data register and a second data register having the same data width. The first data register accepts data from the data stream in accordance with the its data width. Data stored in the first data register is transferred to the second data register. The first data register is then loaded with a portion of the data stream which is contiguous to the data stored in the first data register prior to the transferring. The data in the first and the second data registers is then compared. If the data in the first and the second registers is the same, then the content of a data counter is increased by one. When the content of the data counter exceeds a predetermined value, the system executes a block write command.
