Title: Discrete cosine converting device
Inventor: KAMIYA YOSHIHARU
IPC: G06F17/14
Filed: 1989-07-01
Abstract: PURPOSE:To simplify the circuit constitution by securing the n-stage cascade connection between the 1st and 3rd basic arithmetic circuits based on the 1st and 2nd basic arithmetic circuits set at the first and final stages respectively and the 3rd basic arithmetic circuit set at a stage following the first stage. CONSTITUTION:For the 2<n+1>-degree discrete cosine conversion arithmetic, a basic arithmetic unit A consisting of a circuit which stores temporarily the input data and performs the addition or the subtraction is used together with a basic arithmetic device B consisting of a circuit which stores temporarily the input data and performs the addition or the subtraction to the multiplication results smaller than the number of input data. Then a system is formed with the n-stage cascade connection of such a circuit where the circuit A is set at the first stage and the cascaded circuits B and A set at the stages following the first stage. Then a signal flow chart is computed in response to the value of (n), and a flow chart adverse to the signal flow chart computed in accordance with the value of (n) in the same circuit constitution as that used at conversion in an adverse conversion arithmetic mode. As a result, the circuit constitution is extremely simplified and therefore the discrete cosine conversion and its adverse conversion can be processed in a pipeline method.

Abstract: PROBLEM TO BE SOLVED: To make it unnecessary to use a driving transistor itself to move static electricity go by parallel-connecting electrostatic breakdown protective transistors to the driving transistor and sending the static electricity applied to an output pad terminal to the protective transistors. SOLUTION: A driving transistor having a small current path width and high driving capability is employed. Therefore, if static electricity is applied to an output pad terminal 11 and it is applied to the driving transistor, the transistor is broken down. To cope with this, protective transistors TE1-TE64 are added to let static electricity go to the VSS line side. The protective transistors are turned on to let static electricity go only when static electricity is applied to the output pad. The protective transistors are put in bipolar operation to efficiently let static electricity go.
