Multi-purpose Processor?

I learned about types of processors. There are three types, based on their usages.

CPUs are used for many purposes, because they have Operations Systems to control them, and many applications running under the OSs.
This type is called…I learned only in Japanese term and could not find how to say in English . I had guessed it “multi-purpose processor,” but googling for images with that name showed only FOOD PROCESSORS. oh! I think people in Japan don’t use them so often. I have once bought one when I worked in a lab, to prepare suspension of fine calcite particles. It worked very well. It was made in Germany.
Anyway, this type of Processors can be used for many purposes.

DSPs are for a special use. They are mainly used for multi-media, for example, image processing.
They are very good at multiplying and adding.
For example, for such calculation as below:


DSP does by a set of “multiplying two values, and then add another to the product.”
like this way:


80 percent of the DSPs per year are produced by a vendor called Texas Instrument.
“Thanks for DSPs you could play 3D games. You have to appreciate for DSPs before playing,” the professor said.

There are more specified ones so called as “controller processors”.
Each of them is specific for a certain device.
Most popular examples are fuel controllers in cars. For each model of each company a specific processor is designed.
40 percent of controller processors for cars were produced by a japanese vender called Renesas, but unforunately its main factory in Ibaragi was damaged by the latest earthquake, that is many car factories in the world are worried at.
