MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Higher performance has been achieved by increasing the depth of the pipeline from 3 stages as in the ARM7TDMI to 5 stages. This allows the device to be clocked at a higher rate than the ARM7TDMI.

Detailed explanation-2: -Cortex-X3: the new most powerful ARM core While the previous Cortex-X2 core (discussed in detail here) already removed support for 32-bit mode, Cortex-X3 further benefits from this move.

Detailed explanation-3: -ARM9 – Advanced RISC (Reduced Instruction Set Computing) Machines – microcontrollers are high-performance, 32 bit RISC Core machines. They are extremely fast and powerful, with cores operating at speeds ranging from 150Mhz to 500Mhz.

Detailed explanation-4: -The ARM9TDMI supports the ARM debug architecture and includes logic to assist in both hardware and software debug. The ARM9TDMI also includes full coprocessor support. The ARM9TDMI processor core is implemented using a five-stage pipeline consisting of fetch, decode, execute, memory and write stages.
