***HP and ARM jointly develop real-time execution trace tools for
ARM CPUs
(March 2 )

Hewlett-Packard and ARM announced that they are developing an on-
chip-debugging system that will provide a real-time execution
trace for ARM core-based products.

The co-developed execution trace system consists of an embedded
trace module in the integrated circuit (IC), a trace port
analyser connected to the target system and trace-control
extensions to the software debugger running on any PC. Combined,
these elements provide real-time instruction and a data trace to
engineers using the ARM CPU deeply embedded within their ASICs
(application-specific integrated circuits) or ASSPs (application-
specific standard parts).

This trace system will provide the same visibility for monitoring
the execution of internal CPUs as that supplied by "bond out"
chips, without the high cost or technical difficulties.

The embedded trace module is expected to be available this
spring. Debug products based on this execution trace technology
are expected to be announced later this year, including a trace
port analyser from HP.
