There are many Harvard microcontrollers, DSPs are mostly Harvard, but the key advantages of DSP are:
- most instuctions are single cycle, and 16 or 32 bit devices;
- supports special instructions for signal processing: multiplications, multiply and accumulate the result (MAC) in 1 cycle, data adjusting, representation conversion;

All of the three options are correct.
Internal register width, determines number of bits a processor is capable of handing at a time. Register width in turn dictates data bus width, and number of bits ALU can process in single go.
8-bit processor can very well process 16 & 32-bit data, but not necessarily in a single (...)

Its not a easy question to answer, it depends entirely of which processor you are using.

The clock frequency is devided by 2 inside the 8085 microcontroller ..
Frankly, I don't recall any advantage of deviding the clock frequency, and it is more like an artifact of the 8080 arangement, where the latter used to use 2-phase clock, generated by an external clock IC, the 8224, to perform reading and writing cycles using another external

As far I know I don't think that you could find a faster way to test the status of a I/O line using a commercial CPU: usually the status of processor's IO line is mapped to a specific bit in one (or more depending on the IO pin count) CPU register. So I suppose that 2 clock cycles are the minimum overhead you could expect to acquire this informatio

Depends on your application. If you're just doing a single task a 2GHz single core would be faster. If you're multitasking, the dual-core would probably be faster.

DSPs are optimized for speed and DSP. For example, most DSPs execute all their instructions in a single machine cycle. Also, DSPs have instructions specifically designed for DSP, such as "MAC" (multiply and accumulate) which execute in a single machine cycle.

Originally the JIFFY was the time interval between system timer interrupts, however today it's referred to as the software clock and based on the kernel variable HZ. The value of HZ ranges from 1ms to 10ms, depending on the speed of the processor with 4ms being the default. JIFFIES is the running count of each JIFFY.

Many times we require precise internal time delays between two actions this can be accomplished using software techniques like Loop Technique but these delays keep the processor occupied because of which other important functions cannot be done. To relieve the processor of this burden we can use TIMERS provided by the controller. 8051 has two inter

DC-bus current ripple depends on load inductance and PWM scheme (2-level or 3-level), but will be generally high for a single phase H-bridge. Assuming sufficient load inductance and preferable 3-level scheme, the DC-bus "sees" the 30 A motor current switched on and off, resulting in 15 A rms ripple current at 50% duty cycle.
