MicroBlaze is the trade name for a soft processor core designed for Xilinx FPGAs (field-programmable gate arrays). An FPGA is an IC (integrated circuit) designed for configuration" in the field" by the user. FPGAs can implement any logical function that an ASIC(application-specific IC) can do. MicroBlaze enables more than 70 user-configured options. Examples include cache size, pipeline depth, memory management, and bus interfaces. The configuration wizard, which takes the form of a GUI (graphical user interface), delivers instant feedback through a meter display on resource utilization and performance. Other notable features include: (1) Fault tolerance. (2) ECCs (error correction codes). (3) FPU (floating point unit). (4) Instruction and data caches. (5) Low-latency interrupt mode. (6) Endian conversion support. (7) Hardware exception support. (8) Edge- or level-triggered interrupt signaling. (9) Ease of debugging
