Title: Error processing system
Inventor: TATEISHI TERUTAKA
IPC: G06F11/00
Filed: 1985-08-23
Abstract: PURPOSE:To avoid an error correction failure by turning ON a modifying bit with respect to data concerned in a buffer memory when a bit error is corrected and moved in the error memory. CONSTITUTION:The move -in data MID transmitted from a main memory MEM is checked whether it has an bit error or not by an error checking circuit CHK. If it has the error, the error-corrected data by the correcting circuit CRCT is selected and outputted. As a signal FOUND is at a level L, the output of a selector SL4 turns out to be a read data RD to an access request source REQ through gates G2 and G3. With the conventional techniques, conditions turning ON the demodified bit M of a memory TAG at the time of moving in only covers the case of a write request, however, said bit M can be turned ON when the the operation detects a bit error in a read request mode.

A difference between a normal operation and a transient operation of the internal combustion engine 10 seems to be dependent on a difference in effective opening area. Accordingly, a basic fuel injection quantity Ti and an effective opening area Al are respectively determined according to a first characteristic on the basis of an engine speed and an intake pressure detected by sensors 34, 38, and second characteristic. Meanwhile, the present effective opening area A2 is obtained on the basis of a throttle opening degree and an intake pressure. The basic fuel injection quantity Ti is multiplied by a ratio A2/A1 of the effective opening areas, thus obtaining an output fuel injection quantity.
