Functional Safety Solutions

AUTOSAR Solutions

High Perfoemance

High-performance CPU core

Greatly improved response performance for frequently used interrupt handling

  • Batch save/restore of multiple registers
    Stop currently running program in an instant
    Resume from interrupt handling in an instant
  • Branch prediction mechanism
    Predict the flow of a program using a learning function
  • High-speed flash access
    Read and run the next program in an instant
Low power consumption

Comparison of power consumption at same operating frequency

Thorough low power capabilities contribute to reduced overall power consumption of automobiles

  • Reduced operating power
    Use of 40nm process enables finer circuitry and reduced operating power
  • Reduced leakage power
    Use of low leak transistor reduces leakage power
  • Reduced standby power consumption
    Cut power to circuits that are idle during standby to further reduce power consumption
Multi-core technology

Low power consumption and high performance are realized using multi-core technology.

  • Cores performing functional safety, high-speed calculation, and input/output processing can be combined to achieve a high-performance core configuration.

Three types of cores which play different

High Scalability

Scalability

Scalable CPU core, memory, and peripherals allow reuse of software resources

  • Integrated peripheral function IPs and scalability
    • General specifications of basic IPs (serial, counter, etc.) have been refined from existing specifications, and will continue to retain compatibility in the future
    • Specifications of differentiated IPs (engine control, motor control timer, etc.) have been evolved even further to help increase the competitiveness of the customer's product

PWM: Pulse Width Modulation
LVD: Low Voltage Detection
CAN: Control Area Network
LIN: Local Interconnect Network
FlexRay: An in-vehicle network (in-vehicle LAN) standard
