By combining "TRICORE" and "Aurix Accelerator Suite", the performance of the necessary processing can be improved [Enlarged] Source: Infinin

　Infinnion Technologies Japan (Infininon) announced on January 18, 2021 the Aurix TC4X, a new family of the in -vehicle microcomputer equipped with the original core "TRICORE".It emphasizes that it is a product that keeps the trends in the automotive industry in mind, such as ADAS (advanced driving support system), E mobility, and next -generation E/E (electric/electronic) architecture of automobiles.AURIX TC4X functions that meet the requirements of next -generation E/E architecture.8 "is newly adopted.The operating frequency was up to 500MHz, which improved the performance by about 60 % compared to the previous generation core.The memory capacity is up to 25m bytes.In addition, "Aurix Accelerator Suite" has been prepared as an accelerator that is responsible for AI (artificial intelligence) and communication -related processing.By combining new tricore and these accelerators, we will respond to the requirements needed for next -generation cars, such as AI processing, connected, and security.For the type of accelerator, the PPU (parallelprocessing Unit), which performs parallel processing for AI, switches the routes of different types of network signals (= routing), "DRE (Data Routing Engine)", and signal processing.There are "SPU (Signal Processing Unit)" to be performed.In order to further improve real -time control, a high -speed EGTM timer and a high -solution PWM (pulse width modulation) have been added, and an interconnect connected to the PPU with a low delay has been added."These are the axis of the AURIX microcomputer, which has been adopted from the powertrain area," said Toshiro Kida, a product management manager in charge of Microcomputer, Infinnion Automotive Business Headquarters."Especially in the connection between the processor unit and the actuity such as the timer, the processing in the real world does not feel fast if the delay is high, so we added a new low -delay local bus."In addition to providing DRE accelerator, 5Gbps (bit/second) Ethernet, PCI Express, 10BASE-T1S, Can XL, etc. have also expanded.An Ethernet bridge was also added.Thus, "Realizing safety critical real -time communication while reducing the communication load of the CPU" (Mr. Kidaji), Aurix TC4X is looking for next -generation E/E architectures such as domain and zone type.Up to eight virtual machines can be built."This will make it easier to" replace "the ECU function with the change in the e/e architecture."If you replace the functions of the conventional ECU with Central ECU, using a virtual machine will allow you to install up to eight different applications, reducing the need for interference verification. If there is no such function, it will be.AURIX TC4X's "Synopsys Virtualizer Development Kit" in Synopsys's "Synopsys Virtualizer Development Kit" in Synopsys's "Synopsys Virtualizer Development Kit" in order to shorten the development period by consolidating each function of the ECU at a stretch and rebuilding the software.Prototype is possible.For this reason, you can start development without hardware."Even if there is no silicon, it is possible to develop and verify in a PC environment (Kidaji).If you have a real device, you can start developing with Synopsys's SDK (software development kit) "ARC Metaware Toolkit for Aurix TC4X".AURIX TC4X has launched a sample of 28nm generation products to preceding customers.
