Processor core does not directly control goroutines in Go. Goroutines are lightweight threads managed by the Go runtime, not by the OS kernel. The Go runtime contains a scheduler that maps many goroutines to a smaller number of system threads (OS threads). This scheduler operates in user space and distributes the execution of goroutines across available threads, while the processor core executes these system threads, switching them according to standard OS scheduling mechanisms.

Thus, interaction and management of goroutines occur at the Go runtime level, while the processor core ensures the execution of system threads on which goroutines run. This allows efficient resource utilization and quick switching between goroutines without the costs associated with context switching at the kernel level.

Example: the Go runtime launches several goroutines, scheduling their execution on multiple system threads, and the processor core switches these threads according to standard OS scheduling algorithms.
