Arm Holdings Plc and Hewlett-Packard Co are working together to develop real-time system-on-a-chip debugging tools. The firms claim that the trace execution system they have developed will allow faster and cheaper debugging of ASICs especially in the cellular telephony, hard drive and automobile-specific chip markets – all areas where ARM expects to see revenue growth in 1999. The system consists of an embedded trace module in the integrated circuit, a trace port analyzer connected to the target system and trace-control extensions to the software debugger. The companies expect to issue the first products based around the system in late Spring of this year.
