Write a program to evaluate the following expression using an accumulator machine: A = B + C * D * E + F 7m jun2006

Write a program to evaluate the following expression using an accumulator machine: A = B + C * D * E + F     7m jun2006   Accumulator Architecture: An accumulator is a specially designated register that supplies one instruction operand and receives the result. The instructions in such machines are normally one-address instructions. The popular… Read More »

Explain the micro-instruction encoding methods with the help of suitable diagrams 10m Dec2005

Explain the micro-instruction encoding methods with the help of suitable diagrams. If a machine has a very large number of instructions and registers, which of the two encoding methods is preferred? 10m Dec2005  The characteristics of highly encoded and unencoded micro-instructions:- Unencoded micro-instructions  One bit is needed for each control signal; therefore, the number of… Read More »
