LogiCORE IP XPS HWICAP (v5.01a) Data Sheet(DS586) - 5.01a English - This product specification describes the functionality of the HWICAP core for the Processor Local Bus (PLB). The XPS HWICAP (Hardware ICAP) IP enables an embedded microprocessor, such as the MicroBlaze or PowerPC to read and write the FPGA configuration memory through the Internal Configuration Access Port (ICAP) at run time, which enables a user to write software programs for an embedded processor that modifies the circuit structure and functionality during the circuit’s operation.
