Logic and math for rc cars

When it comes to rc cars, there is a lot of Arithmetic and logic involved. There are units as processors that are basically circuits. They perform thanks to logical and mathematical operations.

Mathematics and logic help rc cars function. In fact in many cases has changed its name to "math coprocessor", although this is a term that emerged to name a special type of processor that is connected directly to traditional processor. Its impact on processor performance is also important because, depending on their power, more or less complex tasks can be done in very short times, such as floating point calculations.

Buses

The so-called buses help immensely. They are the means of communication used by the different components of the rc cars controller and processor to exchange information with each other, eventually the buses or part of them will be reflected in the package pins of the processor.

In the case of microcontrollers, it is common for buses are reflected in the encapsulation of the circuit, since these are intended primarily to E / S general purpose and system peripherals.

There are three types of buses:

-         Address: Used to select the device with which you want to work or in the case of reports, select the data you want to read or write.

-         Control: Used to manage the various reading and writing processes controlling the operation of system devices.

Instruction Set

Although not listed in the schema, we could not leave the set and instruction set out of this feast, because this element can determine what the processor. It defines the basic operations you can perform the rc cars processor, which are conjugated and organized what is known as software. The instruction set are being like the letters of the alphabet, the basic element of language, which allows properly organized write words, sentences and how the program comes to mind.

There are two basic types of instruction channels sets, which determine the processor architecture: CISC and RISC. Within CISC microcontrollers we can find the popular Intel family and Z80 -51, although currently there are CISC-RISC versions of these microcontrollers, which seek to take advantage of RISC processors while maintaining backward compatibility with CISC type instructions.

Memory

Earlier we saw that the memory in the microcontroller must be located within the same package, this is the case most times, because the basic idea is to keep the bulk of the system circuits within a single integrated.

In memory microcontrollers is not abundant, this will not find Gigabytes of memory as personal computers. Program memory typically should not exceed 16 K-volatile memory locations for instructions and RAM will not even exceed 5 kilobytes.

In the case of program rc cars channels memory using different technologies and the use of one or another, it depends on the characteristics of the application to develop, then describes the five existing technologies.
