Overview

The MicroBlaze™ CPU is a family of drop-in, modifiable preset 32-bit/64-bit RISC microprocessor configurations. System designers can leverage the Vitis™ core development kit in 2019.2, or the Eclipse-based Software Development Kit (SDK) in 2019.1 or earlier to start developing for the MicroBlaze processor using select evaluation kits, with no prior FPGA experience. The MicroBlaze processor meets the requirements of many diverse applications including Industrial, Medical, Automotive, Consumer, and Communications markets.

To help you quickly deploy your application, the MicroBlaze processor includes three preset configurations analogous to familiar processor classes.

  • Microcontroller: Suitable for running baremetal code
  • Real-Time Processor: Deterministic real-time processing on an RTOS
  • Application Processor: Embedded Linux capable

Experienced FPGA designers can use the Vivado™ HL Edition design tools to target the MicroBlaze processor to any supported AMD device at no extra cost. Starting from one of these configurable presets, further customization is possible from a variety of specific processor options and a catalog of driver-enabled drag n’ drop peripherals such as PWMs, UARTs, DMAs, serial interfaces, to satisfy the specific needs of the application. It is also available as part of legacy IDS embedded edition for older FPGA device families like Spartan™ 6.
