SoC fabric extensions for configurable memory maps through memory range screens and selectable address flattening

摘要

Described are various SoC fabric extensions for configurable memory mapping. A memory request datapath may transmit a memory request. A first circuitry may identify any memory request having an address between a base-address and limit-address. A second circuitry may transmit to a memory interface any memory request that is identified by the first circuitry, and to apply a default memory access protocol to any memory request that is unidentified by the first circuitry. A third circuitry may modify an address of a memory request when both a multiple-memory-interface indicator and an address-flattening indicator are asserted.
