Core Operations

Three registers work in concert: M holds the multiplicand, A accumulates the result, and Q processes the multiplier. Each cycle examines bit patterns, determining whether to add, subtract, or maintain current values.

01
10 −M

Pattern Recognition

When encountering ’10’, subtract M from A

02
01 +M

Pattern Recognition

When encountering ’01’, add M to A
