Cpu cache ecc
WebHence, an ECC memory can support the scrubbing of the memory content. Namely, if the memory controller scans systematically through the memory, the single bit errors can be detected, the erroneous bit can be determined using the ECC checksum, and the corrected data can be written back to the memory. Overview [ edit] WebSuch CPUs (microcontroller is better name) also have integrated testing and self test like BIST (built in self test) on CPU, peripherals and memory. Of course, their integrated memory (RAM, FLASH) have ECC. For example SpaceX Falcon 9 has triple redundancy system build around 3 dual core x86 CP Continue Reading 2 Ira J Perlow

WebJan 22, 2024 · Recent CPUs from Intel and AMD implement a machine-check architecture that detects and reports hardware issues, including system bus errors, RAM (ECC and parity) errors, and other CPU errors. There are a set of model-specific registers (MSRs) that are used to report errors. WebMay 27, 2024 · The CPU L2 Cache ECC Checking BIOS feature enables or disables the L2 ( Level 2 or Secondary) cache’s ECC ( Error Checking and Correction) capability, if available. Enabling this feature is recommended because it will detect and correct single-bit errors in data stored in the L2 cache.
Many CPUs use error-correction codes in the on-chip cache, including the Intel Itanium, Xeon, Core and Pentium (since P6 microarchitecture) processors, the AMD Athlon, Opteron, all Zen- and Zen+-based processors (EPYC, EPYC Embedded, Ryzen and Ryzen Threadripper), and the DEC Alpha 21264.
