Workload and traffic model
Turn core counts and clock targets into a workload model with dependencies, cache misses and sharing. Core count alone does not establish instructions per cycle or application throughput.

Article labels this the flash die and states its size.
Start with documented specifications, then use the study prompts below. The prompts are engineering guidance, not a claim about this product’s private RTL or physical implementation.
Turn core counts and clock targets into a workload model with dependencies, cache misses and sharing. Core count alone does not establish instructions per cycle or application throughput.
Choose a representative producer/consumer path and specify acceptance, ordering, backpressure, outstanding capacity and reset recovery. Turn these contracts into assertions and test scenarios before optimizing the datapath.
Obtain macro abstracts, pin maps, timing libraries and activity-based power estimates. Explore macro proximity, routing channels and power-grid reachability together. An annotated die photograph can suggest study questions, but cannot supply a netlist, PDK or signoff constraints.

This record has identification and source evidence. A deeper architectural article has not yet been written. Visible patterns alone do not establish block functions, capacity or an internal protocol.
ZeptoBars identifies both photographed dies as components of one GD32F103CBT6 package. This relation is scoped to the documented specimen; it does not establish the implementation of every GD32 SKU.
