Q. Explain about Control Memory Organization?
One of the simplest ways to organize control memory is to organize micro-instructions for different sub cycles of machine instruction in memory. The Figure below demonstrates such an organisation.
Figure: Control Memory Organisation
Let us give an illustration of control memory organization. Let's take a machine instruction: Branch on zero. This instruction causes a branch to a specified main memory address if result of the last ALU operation is zero which means zero flag is set. Pseudocode of micro-program for this instruction would be;
Test "zero flag" If SET branch to label ZERO
Unconditional branch to label NON-ZERO
ZERO: (Microcode that causes replacement of program counter with address offered in instruction)
Branch to interrupt or fetch cycle.
NON -ZERO: (Microcode that can set flags if desired indicating branch hasn't taken place).
Branch to interrupt or fetch cycle. (For Next- Instruction Cycle)
Q. Explain the Use of functions in parallel programming? include "pvm3.h" main() { int cc, tid, msgtag; char buf[100]; printf("%x\n", pvm_mytid());
VuGen have two options to help debug Vuser scripts-the Run Step by Step command and breakpoints. The Debug settings in the Options dialog box permit us to verify the extent of the
A1->A2A3 A2->A3A1|b A3->A1A2|a
Use the input capture to control the digital clock. In this part, there will be two switches to control the clock, one is for starting the clock and one is for stopping the clock.
