EKA1

EKA1 (EPOC Kernel Architecture 1) is the first-generation kernel for the operating system Symbian OS.^[1] EKA1 originated in the earlier 32-bit operating system EPOC.^[2] It offers preemptive computer multitasking and memory protection, but no real-time computing guarantees, and a single-threaded device driver model.^[2][3] EKA1 was replaced by EKA2 as the default kernel starting with Symbian v9.^[3]
