1.2.2. Target Access interface

RealView Debugger works with either a hardware or a software debug target. An ARM development board communicating through RealView ICE or Multi-ICE® is an example of a hardware Target Access. RealView ARMulator® ISS and Instruction Set System Model are examples of a software Target Access.

Each Target Access processes requests from the client tools to the target. A Target Access might be a JTAG interface, a simulator, or a ROM monitor.

For details on how to connect to targets, see the RealView Debugger v3.0 User Guide.

For details on how to configure targets and connections, see the RealView Debugger v3.0 Target Configuration Guide.

Instruction Set System Model

Instruction Set System Model (ISSM) simulates Cortex™-A8 and Cortex-M3 models. ISSM runs on the same host computer as the debugger, and includes facilities for communicating with the debugger.

RealView ARMulator ISS

RealView ARMulator ISS (RVISS) is an Instruction Set Simulator (ISS). It simulates the instruction sets and architecture of ARM processors, together with a memory system and peripherals. You can extend it to simulate other peripherals and custom memory systems.

RVISS runs on the same host computer as the debugger, and includes facilities for communicating with the debugger. Alternatively, using RealView Simulator Broker, you can connect to RVISS on a remote host.

Note

RVISS is not the same as the ARM Developer Suite (ADS) ARMulator supplied with previous releases of RealView Debugger.
