Abstract
This invention relates to a device for converting bit strings from a first resolution to a second resolution suitable for application, in particular, on peripherals such as printers, scanners or facsimile machines. The device comprises a source register 31 in which a string of bits to be converted is stored by a CPU 11, a destination register 32 from which the CPU 11 extracts the converted string, and a pair of control registers 21 and 22 which cooperate for converting bit by bit the bit strings from the source register 31 to the destination register 32. The control registers 21 and 22, the source register 31 and the destination register 32 operate independently from the CPU 11 used and at a clock rate (clk2) greater than that (clk1) of the CPU 11, thereby permitting extremely fast conversion times.
