Microprocessors :

Analog devices like transistors and diodes lead to opamps and analog computing. This takes more parts but with fast devices, it is real time. Then came Logic and Digital Circuits, here also big systems will take too many parts.  A very Old hp Logic Analyzer instrument, could be HP1607A, had more than five large PCBs, Toggle Switches and numerous 74F00 TTL Chips.

Microprocessor and Microcontroller chips - Solutions with AVR and PIC are popular with Electronic Enthusiasts. TI, NXP, STMicro and Infineon have many uC and ARM products. 

The 8052 SBC

"The SBC is a single-board computer designed to be both useful and instructive in illustrating certain concepts commonly encountered in 8052-based development. Designed to compliment The 8051/8052 Microcontroller Book that was authored by Craig Steiner, the webmaster of "

Then came the solution the Microprocessor.  Here the entire system goes into the firmware and a Hardware. Tool Set in the Microprocessor made up of Logic and Math, sequentially used to perform the same operation that would require innumerable Gates in a plain hardware digital circuit. But as it performs the operations one after another, it takes time, hence the speed is defined by the CPU Clock Speed and Bus width.

When the External RAM and EPROM and other peripheral devices moved into the main package, MicroController were born. When more external devices merged with the MicroController. It formed a nearly complete computer, this is known as the SOC.

Now soft cores of some popular chips and new structures are available as IP. These can be integrated in your FPGA or ASIC design. The speed and capabilities of a Microcontroller system depends on how Intelligent the hardware is. Less code needs to be written, when more standard software routines are implemented as hardware blocks. One example is the Numeric processor 387 integrating with uC 386 to form 486 with other enhnacements. Another example is the serial port or UART in 8051, this had to be coded in the 8748.

Digital and Embedded Systems Design

An Embedded Microcontroller or DSP system is made of Chips, Circuits and Firmware. The digital voltage levels, speed, bus width, fan out, power consumption are some factors that a designer has to keep in mind. As portable and wireless gadgets are becoming more popular, RF, Ethernet and Energy Efficient Design aspects should be studied. Power electronics and Analog Circuits knowledge is used around the system, all this is integrated to make an instrument, equipment or gadget.
