Draw an SM chart for the BCD-to-binary converter of Problem 4.13.

Data from Problem 4.13.

This problem involves the design of a BCD-to-binary converter. Initially a 3-digit BCD number is placed in the A register. When an St signal is received, conversion to binary takes place and the resulting binary number is stored in the B register. At each step of the conversion, the entire BCD number (along with the binary number) is shifted one place to the right. If the result in a given decade is greater than or equal to 1000, the correction circuit subtracts 0011 from that decade. (If the result is less than 1000, the correction circuit leaves the contents of the decade unchanged.) A shift counter is provided to count the number of shifts. When conversion is complete, the maximum value of B will be 999 (in binary). Note: B is 10 bits.
