This week brought substantial performance improvements to AtomVM's JIT compiler alongside expanded hardware connectivity options and critical stability fixes.
The JIT compiler received major optimization work through two connected efforts. PR 2322 replaced linear list lookups with logarithmic map operations for hot data structures and batched small instruction emissions to reduce NIF dispatch overhead. PR 2328 factored shared native register bookkeeping across multiple…
Platform support expanded significantly with USB CDC port driver implementation across ESP32, Raspberry Pi Pico, and STM32 platforms in PR 2301. This continues previous work and provides developers with standardized USB communication capabilities across AtomVM's major embedded targets. The change touched multiple…
Several critical stability issues received attention. PR 2325 fixed multiple memory allocation problems that could trigger data corruption, specifically in binary replace operations, zlib compression, and BSD socket receive code. These fixes became apparent with new garbage collection code…
