Abstract
Apparatus for processing data is provided, said apparatus comprising: a main processor ; an instruction transfer register ITR for holding a data processing instruction and accessible via a first serial scan chain SC ; a data transfer register DTR for holding a data value and accessible via a second serial scan chain SC ; debug logic for controlling said main processor , said instruction transfer register ITR and said data transfer register DTR such that a data processing instruction held within said instruction transfer register ITR is passed a plurality of times to said main processor for execution upon a sequence of data values scanned into or from said data transfer register via said second serial scan chain. In this way operational speed of the debug mode is increased since the data processing instruction only needs to be transferred once.
