Abstract: PURPOSE:To perform a fast arithmetic operation on a cyclic code in compression data by applying the ordinary arithmetic operation of a generating function on a non-compression area, and performing the arithmetic operation of a compression area at an acceleration arithmetic matrix circuit in which a computed result is stored in advance. CONSTITUTION:The arithmetic operation of the cyclic code of the non-compression area by a generating function arithmetic part 2 and the arithmetic operation (conversion) of the compression area by an acceleration arithmetic matrix part 16 are performed. The acceleration arithmetic matrix part 16 is a memory which stores plural compression data and the computed result of the cyclic codes for plural data length in advance, and outputs the computed result of the compression data based on the amount and the content of compression data inputted from data buses 11 and 13, and a computed result shift part 14 performs the idle shift of the computed result of the generating function arithmetic part 2 before the compression data is inputted by the amount of compression data based on a generating function. In such a way, it is possible to perform the arithmetic operation of the cyclic code at high speed without recovering the compression area once to the non-compression data, and to detect a data error at high speed by preventing the transfer of the compression data from being interruptted.

Filed: 1982-08-12
Abstract: PURPOSE:To prevent incomplete combustion at the deceleration of an engine, by using the supercharging second intake passage of an intake device of partial supercharging type and a shutoff valve in the passage also as means for coping with the deceleration. CONSTITUTION:In deceleration, no output is sent from a supercharged operation detecting circuit 30 to a pulse width generation circuit 35 so that no pulse is supplied from the circuit 35 to a drive circuit 37. However, an output is sent from a deceleration detecting circuit 27 to a holding circuit 36 so that the circuit 36 acts to cause a prescribed electrical current to flow to the drive circuit 37. As a result, a shutoff valve 11 is shifted in a direction to close and then kept at a required degree of opening so that the quantity of intake through a second intake passage 5 is made smaller than a supercharged quantity is supercharged operation. Since the intake is effected through the second intake passage in the deceleration, a mixture is prevented from becoming excessively thick and incompletely burned in the deceleration.
