Abstract

A Universal emulator has a dual port emulation memory which can be connected to any microprocessor target board system via a standard memory socket and to a programmable computer via an interface circuit. The interface circuit contains breakpoint control logic (Fig 3) with an interrupt output signal which can be connected to the interrupt line of the microprocessor target board. An interrupt driven debug routine which can be executed by the target microprocessor allows the status of the microprocessor's registers etc to be viewed on the programmable computer display. The programmable computer is also able to control the operation of the target microprocessor via the breakpoint control logic and a Universal Step/Animate control circuit, USAM. The emulator can be configured for many different microprocessors by personality files supplied on disc, containing information about microprocessor register architecture. <IMAGE>
