The Xtensa LX7 release also provides new tools, including a new hardware floating-point application binary interface (ABI) for increased floating-point C/C++ performance, as well as compiler and C library enhancements to add C99 complex float support.
Additional memory protection choices include:
- Support for ACE-Lite to facilitate I/O coherence in heterogeneous multi-processor designs
- Error-correcting code (ECC) on AXI interface to detect and correct bit errors in system memory
- Security to indicate the privilege and security level of the bus transaction
- Exclusive access for data integrity, preventing shared memory overwrite issues
- New automatically generated integrated DMA (iDMA) controller internal to the Xtensa processor to offload memory-to-memory data transfer operations from the processor and hide system bus latency. Includes a software library for ease-of-programming.
- New fine-grained memory protection unit (MPU) with programmable region sizes and access protections
