A CPU processor or central processing unit controls the functions of most electronic products. The CPU accepts the input data, processes the information and sends it to the component that is in charge of executing the action. CPUs are also known as microprocessors and are at the center of any computer system. Although CPUs are most often thought of as a computer chip, they can also be found in many other electronic devices including cell phones, hand held devices, microwaves, television sets and toys.

It's impossible :o) You can disable and enable any interrupt source by setting or clearing corresponding bit in proper control register. Show me your code - we will see what can be done wrong.

You can set bit I on SREG by 1 to enable global interrupt or by 0 to disable it.

in c programming you can write

#asm ("sei") //to enable global interupt

#asm ("cli") //to disable global interupt

Cache is a high speed memory which is basically used for the following reason:

As the speed of the main memory is not as much as the speed of the CPU.so just to compensate the speed mistmatch between the CPU and main memory the cache is used in between the two.so whenever the CPU asks for any data its being checked with the cache memory and if present then "cache hit" occurs or else "cache miss" occurs wher the CPU takes the data form the main memory and that data's cpoy is being send to the cache for any further operation where the CPU can request for the same data.

Complex programmable logic device (CPLD) are programmable digital logic devices which are simpler and lesser capacity than FPGA (Field Programmable Gate Arrays) devices. CPLDs have a non-volatile memory (i.e. turning off the power does not require reprogramming of CPLD)

Microcontrollers (uP or MCU) are small and cost effective but self contained computer chips (compared to general purpose processor chips used in personal computers) used for embedded applications in industrial, consumer electronics products and automobiles. Microcontrollers may or may not have inbuilt memory.

CPLDs are used for implementing logic but they do not have a embedded processor like in microcontrollers.

All micro-controllers are going to be difficult to use, because you build your circuits around them, not vice versa. From a programmer perspective, the BASIC Stamp uses PBasic which is very easy to use and understand. The PIC16F84 Micro series uses assembly, but only has 30 commands and is much more powerful IMHO.

just a note: Clarify your question

Bit-addressable registers are registers that its bits can be modified individually. that means if you have register named "ACC" that is bit addressable , you can change its bits (D0 -D7) individually by special instructions SETB and CLR.

ex: SETB ACC.3 ; will set bit number 4 (remember bit 0) in the register

in 8051 there are many bit-addressable registers such as A (ACC), B, SCON, PCON, TCON, p0,p1,p2,p3 .
