EKA1
Template:Short description Script error: No such module "Unsubst".Script error: No such module "Check for unknown parameters". 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]
Much of EKA1 was developed by a single software engineer, Colly Myers, when he was working for Psion Software in the early 1990s. Myers went on to act as CEO for Symbian Ltd.,[3][4] when it was formed to license this kernel and associated operating system to mobile phone makers.[5][6]
