Abstract
In an example, a circuit to manage memory between a first and second microprocessors each of which is coupled to a control circuit, includes: first and second memory circuits; and a switch circuit coupled to the first and second memory circuits, and memory interfaces of the first and second microprocessors, the switch circuit having a mode signal as input. The switch is configured to selectively operate in one of a first mode or a second mode based on the mode signal such that, in the first mode, the switch circuit couples the first memory circuit to the memory interface of the first microprocessor and the second memory circuit to the memory interface of the second microprocessor and, in the second mode, the switch circuit selectively couples the first or second memory circuits to the memory interface of either the first or second microprocessor.
