MicroBlaze

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:

• Fault tolerance.
• ECCs (error correction codes).
• FPU (floating point unit).
• Instruction and data caches.
• Low-latency interrupt mode.
• Endian conversion support.
• Hardware exception support.
• Edge- or level-triggered interrupt signaling.
• Ease of debugging.
