Abstract
A method of changing execution contexts is provided that includes receiving a context selection input. In a first clock phase, the method includes shifting data from a first latch element of a normal execution context to a second latch element of the normal execution context and shifting shadow data from a third latch element of a shadow execution context to a fourth latch element of the shadow execution context. In a second clock phase, the method includes shifting the shadow data of the fourth latch element of the shadow execution context into the first latch element of the normal execution context and shifting the data of the second latch element of the normal execution context into the third latch element of the shadow execution context. In a particular embodiment, the method may include receiving a test mode selection and shifting test data, such as scan test or automatic test pattern generated data, to a test output.
