ROM emulator

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.

This new development environment consists of three integrated components: the Tornado tool suite, a set of powerful tools and utilities on both the host and the target; VxWorks, the industry's most powerful and scalable real-time operating system, which executes on the embedded target processor; and a full range of communications options such as Ethernet, serial line, ICE or ROM emulator for the target connection to the host.
Consequently, designers are forced to make due with lower-cost development tools (such as ROM emulators or development boards) and trade off design efficiency for cost.
Unlike ROM monitors, ROM emulators, low-end emulators and other mid-range ICEs, CodeTAP provides full trace and register visibility (via CPU browser), while being small enough to fit in one's pocket.
The new XRAY Integration Kit, based on Microtec's industry-standard XRAY debugger, enables third-party hardware assist, semiconductor and real-time operating system (RTOS) vendors to seamlessly integrate XRAY with their embedded products, including simulators, monitors, in-circuit emulators (ICEs), ROM emulators and BDM debuggers.
