Major bugs fixed / stability improvements: - Added assertions for valid bank accesses to catch and diagnose invalid memory bank usage earlier, improving runtime safety and reducing debugging time for memory subsystem issues. - Cleanup of legacy interconnect logic (removal of wide-narrow SNAX port logic) to reduce complexity and potential corner-case failures during the sparse interconnect transition. Overall impact and accomplishments: - A significantly more scalable and safer memory interconnect, enabling better throughput potential and earlier error detection in production workloads. - A streamlined toolchain and build environment with up-to-date LLVM and SNAX components, improving compatibility and future maintainability. - Enhanced MLIR-based tensor operations with dynamic indexing and updated SNAX features, enabling more flexible and capable workloads. Technologies/skills demonstrated: - Hardware interconnect design: sparse TCDM, priority arbitration, bank-access safety checks, and runtime assertions. - Compiler/toolchain: LLVM 21.1.1 integration and compatibility improvements. - MLIR/xDSL integration: dynamic indexing enhancements and xDSL bumping. - SNAX ecosystem updates: version upgrades, polling barrier and long addition extension, and dependency alignment.
