Abstract

The present invention discloses an image processor (224) for executing a computer instruction set (280, 290) in the form of an opcode (281), at least one operand (283-285) which is, or indicates the location of data to be processed. The data to be processed consists of a variable length stream of data and each instruction includes a length field (297) containing data specifying the number of items of data to be processed or, if that number exceeds the size of the length field, a predetermined location of a previously allocated storage area at which that number is stored.
