Abstract: Implementing complex digital signal processing (DSP) logic on multi-core hardware matrices requires specialized code synthesis methodologies to avoid runtime deadlock states. This paper details an object-oriented compilation framework developed to parse, analyze, and optimize Synchronous Dataflow (SDF) graphs. The compiler leverages an automated topological mapping engine that extracts concurrency properties and constructs static, periodic schedules at compile time. This process completely removes scheduling execution demands from the target microcontroller. We tested the system by generating production-grade C source code for an array of multi-channel audio filter networks. The synthesized application achieved a 15.6% reduction in code size compared to standard commercial tool suites. Furthermore, internal memory buffer allocations were optimized, reducing memory space demands by 28.3% while maintaining real-time latency profiles of less than 1.2 ms per audio frame block.
