The programming gives the functionality to those device. But the market is not huge, because the world spent less than $5 billion on DSPs on year 2002.So why the huge difference between microprocessors' effect on the economy and their comparatively tiny numbers? That is where programming comes in.
Most microprocessors are much cheaper than that, but then there is always those expensive ones in the market that pull the average price up.That is the the DSP deal? DSP average price is around $6 per chip, but that includes a lot of inexpensive hard-wired modem chips and the like.

The reason for this is that PC processors are expensive (modern Intel CPU can cost $300) and they are sold in large volumes.Taken as a whole, the average price for a microprocessor, microcontroller, or DSP is just over $6. This means that PC processor makes 15% of all the money made from every type of semiconductor from every company everywhere in the world. PC processors are only 2% of all processors in volume, but PC processors are 50% of all processor sales in money. ARM-based chips alone do about triple the volume that Intel and AMD peddle to PC makers. Most (98% or so) 32-bit processors are used in embedded systems, not PCs. This category includes PC processors like Pentium 4 and Athlon, of course, but also dozens of embedded processors such as PowerPC, 68k, MIPS, and ARM chips. But they're not very expensive, so they're less than 15% of the fiscal tonnage.At the opposite end of the scale are-big surprise-32-bit microprocessors. This kind of smallprocessors are found embedded in a wide varierty of electronics devices, ranging from small gadgets and home equipment control to car electronics.Those small controllers areflying off the shelves at the rate of more than 3 billion new chips per year(more than half of the microprocessor sale per units). In the processor arena, it's the 4-bit microcontrollers that are the cheapest.The small 8-bit chips (little old 8051s and 6805s) are the best-selling type of processor. There is difference how different microcontrollers are sold. A tiny 2% sliver of the market is all that processors contribute, but they generate a whopping 30% of the dough. Thirty percent of the world's semiconductor sales come from microprocessors, DSPs, microcontrollers, and programmable peripheral chips. The biggest chunk of the digital business comes from processors butprocessors are only 2% of all semiconductors market. Microprocessors are the core of a computer, but they are used alsoin many other applications (for example embedded devices).
Microprocessors are essential to many of the products we use every day such as TVs, cars, radios, home appliances and of course, computers. PIC computer hardware interfacing projects.
