it is very simple.... there are two parameters clear and load.. when clr is high(1) all the outputs becme zero and when clr is low(0) ff's are ready to work.. now load controls d ckt.. when load is lw and loadbar is high the output of the or gate depends on q0 q1 and q2... nw when the positive edge of clk pulse arise the data is circulated or retained i.e., register conents remain the same.. when load is high and loadbar is low the output of or gate depends on x0 x1 and x2.. nw when positive edge of clk pulse arise x bits reach the ff's and x bits are stored so that q0 q1 q2 = x0 x1 x2.. see the diagram for 3-bit contrlled buffer register and u will understand it.. hope it was useful :)

What is the purpose of buffer register?
here, just the registers are used to store the temporary data in the variables instead of RAM.
What is the difference between latch and buffer?
Latch A latch remembers the last state it was told to with another latchingsignal Buffer A buffer merely strengthens a signal so that it canbe fanned out with integrity or drive a heftier device. Any amplifieris a buffer. It outputs a state only as long as the state persistson its input(s).
What is difference between single double and circular buffer?
single buffer : you read and write on the same buffer, can be messy if both reading and writing take place at the same time.double buffer : you read one buffer and you write the other one. When both reading and writing are complete, the buffers are swapped. It solves the problem of simultaneous reading and writing but requires synchronization.circular buffer : this a buffer with two pointer : read and write. If both pointers are equal, the buffer is empty.For each write operation, the write pointer advances and each time data is read back, the read pointer advances. It is circular because when a pointer reaches the end, it wraps back to the beginning.It may be used to implement a queue which allows simultaneous reading and writing without synchronization as long as the buffer is not full.A double buffer is basically a circular buffer of size 2 and a single buffer is basically a circular buffer of size 1.
What do you mean by buffer in micro processor?
A buffer is merely a temporary storage used in conjunction with computation.
Why gets function gives a warning every time you compile a c program?
It is unsafe. In order to use gets() safely, you need to know how many characters you will be reading to ensure your character buffer is large enough: char buffer[10]; while (gets (buffer) != 0) { ...process buffer... } The above code has undefined behaviour when the number of characters read is 10 or more (you need one character for the null-terminator). This is because the character buffer, str, decays to a pointer (referencing &str[0]) and the function, gets(), cannot determine the number of characters in a buffer by its pointer alone. The gets() function was dropped from the C standard in 2011, however some implementations still include it. To avoid the warning, use the fgets() function instead. This allows you to specify the length of your buffer and (when used correctly) prevents buffer overflow. char buffer[10]; while (fgets (buffer, 10, stdin) != 0) { ...process buffer... }
What is controlled shift register?
a controlled shift register is a register that is shifted and controlled..lol
Instruction Buffer Register?
An Instruction Buffer Register is also known as IBR. It registers a computer's processor or its Central Processing Unit (CPU).

What does buffer full mean on cash register?
it means storage is full.
Write short note on memory buffer register?

What are buffer registers?
A buffer register is the simplest kind of register; all it does is store a digital information temporarily. It holds the contents of the memory which are to be transferred from memory to other components. By acting as a buffer, it allows the central processor and memory units to operate independently without being affected by minor differences in operation. See the related link for more information.
Draw and explain the bloack Daigram of Von Neumann machine?
Block diagram of the von Neumann architecture: MQ, multiplier quotient register; IR, instruction register; IBR, instruction buffer register; MAR, memory address register; MDR, memory data register
How does the Fetch Decode Execute work?
The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.
