ECC : Error Correcting Code

Table of Contents

To increase functional and system reliability, the memories in many device modules and subsystems are protected by Error Correcting Code (ECC), which performs Single Error Correction (SEC) and Double Error Detection (DED). Detected errors are reported via ESM. Single bit errors are corrected, and double bit errors are detected. The ECC Aggregator is connected to these memory and interconnect components which have the ECC. The ECC aggregator provides access to control and monitor the ECC protected memories in a module or subsystem.

SDL provides support for ECC aggregator configuration. Each ECC aggregator instance can be independently configured through the same SDL API by passing a different instance. The safety manual also defines test-for-diagnostics for the various IPs with ECC/parity support. The SDL also provides the support for executing ECC aggregator self-tests, using the error injection feature of the ECC aggregator. The ECC aggregators should be configured at startup, after running BIST.

Features Supported

The SDL provides support for the ECC through:

  • ECC Configuration API
  • ECC self-test API
  • ECC error injection API
  • ECC static register readback API

  • ECC error status APIs

    The SDL ECC module requires a mapping of certain aggregator registers into the address space of the R5F Core. In these cases, the ECC module will use the DPL API SDL_DPL_addrTranslate() to get the address. The application must provide the mapped address through this call. This mapping is required for any ECC aggregator that is used which has an address which is not in the 32-bit address space. The mapping is expected to always be valid because it may be needed at runtime to get information about ECC errors that may be encountered.

There are over 13 ECC aggregators on the device each supporting multiple memories and interconnects.

Error Injection for Various RAM ID types

There are two types of ECC aggregator RAM IDs supported on the device (wrapper and interconnect). The wrapper types are used for memories where local computations are performed for particular processing cores in the device, and the interconnect types are utilized for interconnect bus signals between cores or to/from peripherals.

For wrapper RAM ID types, after injecting an error, the memory associated with that RAM ID needs to be accessed in order to trigger the error interrupt event. It is the application's responsibility to trigger the error event through memory access after injecting the error.
