A SLAVE coprocessor connectable to a MASTER processor and cooperating with at least one external memory. The coprocessor presents an internal memory communicating with an internal data line extending between a first and second interface circuit communicating respectively with the processor and the external memory; the internal memory contains a character composed of a rectangular matrix of pixels corresponding to a digitized alphanumeric character; and the coprocessor presents an electronic arithmetic unit for comparing a character from the internal memory with a reference matrix from the external memory.
