Abstract:
A semiconductor integrated circuit is provided, which includes: a first circuit; a second circuit; a data BUS; and first and second encryption/decryption circuits for encrypting/decrypting data transmitted between the first and second circuits on the data bus. The first encryption/decryption circuit is for encrypting data output from the first circuit, outputting the encrypted data to the data BUS, decrypting an encrypted data received from the second encryption/decryption circuit, and providing the decrypted data to the first circuit. The second encryption/decryption circuit is for decrypting the encrypted data received from the first encryption/decryption circuit, providing the decrypted data to the second circuit, encrypting data output from the second circuit, and outputting the encrypted data to the data BUS.

PURPOSE: An integrated circuit capable of protecting an internal bus input/output data is provided to prevent input/output data between embedded circuit blocks from being monitored by a non-approved person. CONSTITUTION: A CPU circuit block(110) includes a CPU(111). A RAM circuit block(120) includes a RAM(121). A data bus(130) is provided for a data transmission/receipt between the circuit blocks. The CPU circuit block(110) includes a random number generator(113) which generates 4-bit random number by responding to a clock signal(CLK). The CPU circuit block(110) also includes the first scrambler(112) which changes an array of lower 4-bit out of 8-bit data being output from the CPU(111) in accordance with the random number, outputs the 4-bit to the data bus(130), restores the array of bit of data being inputted from the RAM circuit block(120) through the data bus(130), and supplies the restored array to the CPU(111). The RAM circuit block(120) includes the second scrambler(122) which restores the bit array of 4-bit data being inputted from the CPU circuit block(110) into the original array through the data bus(130) in accordance with the random number generated in the random number generator(113), supplies the original array, changes an array of lower 4-bit out of 8-bit being output from the RAM(121) in accordance with the random number, and outputs the changed array to the data bus(130).

Abstract:
PURPOSE: A method for measuring quantity of exercise and a display apparatus adopting the same are provided to calculate a motion analogous degree representing a comparison between a motion image of a user and a sample motion image, which is previously stored in association with a sample value of exercise quantity, and to calculate the exercise quantity of the motion of the user using the calculated motion analogous degree. CONSTITUTION: A display apparatus obtains a motion image by photographing the motion of a user (S320). The display apparatus calculates the motion analogous degree of the obtained motion image and a sample motion image that is mapped with a particular exercise quantity and then stored (S330). The display apparatus calculates exercise quantity of the motion of the user using the calculated analogous degree (S340).
