SOC FABRIC EXTENSIONS FOR CONFIGURABLE MEMORY MAPS THROUGH MEMORY RANGE SCREENS AND SELECTABLE ADDRESS FLATTENING

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. 所描述的是用于可配置存储器映射的各种SoC结构扩展。存储器请求数据路径可传送存储器请求。第电路可识别具有处于基地址与限制地址之间的地址的任何存储器请求。第二电路可向存储器接口传送第电路所识别的任何存储器请求，并且将默认存储器访问协议应用于第电路未识别的任何存储器请求。第三电路可在多存储器接口指示符和地址平坦化指示符均被断言时修改存储器请求的地址。
