Key features
- Fast with high performance - the processor s 8-stage, dual-issue pipeline combined with instruction pre-fetch and branch prediction achieve fast instruction execution.
- Highly deterministic - advanced features such as Tightly-Coupled Memory (TCM), Vectored Interrupt Controller (VIC) port, and Low Latency Interrupt Mode (LLIM) make the Cortex-R4 highly deterministic with accelerated interrupt entry.
- Reliable - error handling built into the core; Integrated Memory Protection Unit (MPU), Error-correcting code (ECC) memory, and dual-core lock-step configuration ensure the Cortex-R4 processor’s reliability to handle errors.
- Energy efficient and cost effective - supports a highly flexible and efficient two-cycle local memory interface, enabling SoC designers to minimize system cost and energy consumption
