ROM emulator

A circuit that helps debug a ROM chip by simulating the ROM in RAM memory. The RAM circuit plugs into the ROM socket, and since RAM can be rewritten, whereas ROM cannot, programming changes can be easily made and tested.

The Tornado development platform consists of three integrated components: the Tornado suite of tools, a set of cross-development tools and utilities; the VxWorks run-time system, a scalable RTOS; and a number of host-target communications options, such as Ethernet, serial line, in circuit emulator (ICE) and ROM emulator.
The Tornado development environment is composed of three highly integrated components: the Tornado suite of tools, a powerful set of cross-development tools and utilities on both the host and the target; the VxWorks(R) run-time system, a high-performance, scalable real-time operating system that executes on the target processor; and a full range of communications software options such as Ethernet, serial line, in-circuit emulator (ICE), ROM emulator, or custom backend for target connection to the host development system.
