摘要: A processing sub-system is configured to execute a program using a set of virtual memory addresses to reference memory locations for storage of variables of the program. A programmable logic sub-system is configured to implement a set of I/O circuits specified in a configuration data stream, each of the I/O circuits having a respective ID and configured to access one of the variables. A memory management circuit is configured to map the virtual memory addresses to physical memory addresses of a memory and map IDs to the physical address used to store the corresponding variables. A TLB is configured to receive a memory access request, from the I/O circuits, each request indicating an ID and provide, to the memory, a memory access request indicating the physical memory address that is mapped to the ID.

摘要: 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.
