<p>PROBLEM TO BE SOLVED: To reduce a circuit scale while high-speed data process is realized with small power consumption, and carry out many kinds of tests for the circuit easily. SOLUTION: A 1/2 pixel skipping circuit and a 0/1 repeating circuit are provided in a scrambling code generator, and superfluous multiplication circuits can be eliminated to realize small size of circuit scale, high processing speed, and low power consumption. By turning off (multiplication is through) a channelization code, by turning off (complex multiplication is through) scrambling code or by turning off both sides, a calculation result necessary for many kinds of tests can be generated outside the circuit, and verification for many kinds of tests can be carried out easily.</p> |
