Texas Instruments Digital Design Engineer interview questions

Texas Instruments (Digital ) Interview Experience : 1. Introduce yourself 2. Asked to explain a course project . Asked details of it including the finer implementations . They went quite deep into the project. 3. Asked to explain another project. 4. Draw a circuit to count the number of 1’s in a vector. Asked to optimise it after I gave a not so optimum solution. 5. Draw a circuit to implement a given pattern (don’t remember it now) . Input and output was given . You have to detect the pattern from input and output and draw the digital circuit accordingly. The pattern was such that for the even no. of clock pulses , out=in but for odd clock pulses , out =in_delayed_by_2 (in value 2 cycles ago)
