Abstract
A monitoring apparatus includes a programmable event filter (18) which identifies the occurrence of a predetermined signal (such as a memory address location) on a signal path of a programmed device such as a CD-i player. On detection, one or more successive bus signals are captured in a buffer (20) and subsequently written to storage (14) for processing by an internal processor (10) or the bus signals are sent over a bidirectional communications link (16) to a host device implementing suitable data processing algorithms. A particular use for the monitoring apparatus is in non-intrusive debugging of programmed devices taking account of their operating systems.
