An Integrated Circuit Modular Library for Angle-Based Engine Control 922127

An integrated circuit modular library designed specifically for tracking position and triggering ignition, injector, and variable valve outputs of an internal combustion engine has been developed in a mature standard cell CMOS technology for incorporation into electronic Engine Control Units (ECU). The modules are configured into an intelligent peripheral device that subsequently off-loads the ECU microprocessor of the many interrupts and calculations during engine operation. The resultant configuration of ECU microprocessor and intelligent peripheral yields a high throughput system that rivals the performance of RISC (Reduced Instruction Set Computer) based powertrain controller methodologies at a reduced total system cost.
