TL;DR: This specialized hardware assists program debugging and testing and program performance evaluation and programperformance evaluation.
Abstract: This specialized hardware assists program debugging and testing and program performance evaluation. It is installed like any other peripheral device.
TL;DR: A true distributed debugger should handle the sequence of events that lead to an error in a distributed program can be quite complex to model and difficult to capture and recreate using a serial debugger.
Abstract: Distributed debugging via serial debuggers suffers from two problems: i. serial debuggers are made for one process running on a single processor, whereas distributed programs contain many processes running on different processors in a network. 2. the sequence of events that lead to an error in a distributed program can be quite complex to model and difficult to capture and recreate using a serial debugger. A true distributed debugger should handle both problems easily.
TL;DR: A software tool for assembly-language programming which provides an improved user interface by making use of the facilities of modern visual display units is described, Graphbug, which is designed for the Z80 microprocessor and runs under the CDOS operating system.
