Emulation Technique MCQ Quiz – Objective Question with Answer for Emulation Technique

The ICE or in-circuit emulation is one of the traditional methods used to emulate the processor in the embedded system so that the software can be downloaded and can be debugged in situ in the end application.

The SDS is one of the simulation tools used in embedded systems. CPU simulator and the low-level simulator are the other kinds of simulators used in the embedded system design.

The in-circuit emulation does not have the ability to get a hundred individual signal cables into the probe. This problem comes under the physical limitation of the probe, that is as the density of the processor increases the available sockets which provide good electrical contacts are becoming harder which causes a restriction to the probe.

The JTAG is a joint test action group which is an electronics industry association that developed the interfacing port that is standardized for testing the devices.

The JTAG can access all the hardware within the system. They provide a way of taking over the pins of a device and allow the different bit patterns to be imposed on the pins which allows other circuits to be tested with the imposed pins.

The JTAG works by using a serial port and clocking data into a shift register and the output of the shift register drives the pins under the control of the port.

The OnCE is an on-chip emulation which is a debugging facility used in the digital signal processor chips.

The on-chip emulation provides a debugging facility in the DSP chips. The OnCE is developed for Motorola’s DSP 56x0x family.

The debugging support to the processor enables the processor to be a single stepped and breakpoint under remote control from a host or the workstation. This facility can provide the provision of the debug ports.

The on-chip emulation can access additional registers by using a special serial port within the device that provides control over the processor and access to its internal registers.
