Micro Blaze Soft Processor Core

Micro Blaze™ is the industry-leader in FPGA-based soft processors, with advanced architecture options like AXI or PLB interface, Memory Management Unit (MMU), instruction and data-side cache, configurable pipeline depth, Floating-Point unit (FPU), and much more. MicroBlaze is a 32-bit RISC Harvard architecture soft processor core that is included free with both Vivado Design Edition and IDS Embedded Edition. Highly flexible architecture, plus a rich instruction set optimized for embedded applications, delivers the exact processing system you need at the lowest system cost possible.

High-Performance, Small Footprint, or something In-between?

MicroBlaze contains over 70 user-configurable options, enabling virtually any processor use case from a very small footprint state machine or microcontroller to a high performance compute-intensive micrprocessor-based system running Linux, operating in either 3-stage pipeline mode to optimize size, or 5-stage pipeline mode to optimize speed delivering faster DMIPs performance than any other

Extreme configurability is at the heart of MicroBlaze’s flexibility, but you don’t have to memorize a manual to learn how to configure MicroBlaze. Through the MicroBlaze Configuration Wizard included in Xilinx Platform Studio – a few mouse clicks lets you quickly select between six common microprocessor use models. The configuration wizard delivers instant feedback through a meter display on resource utilization and performance, and runs in wizard mode for fast setup, or advanced mode for access to the lowest level details.

New version 8 features expand MicroBlaze capabilities even further

Over the past year Xilinx has added new features to MicroBlaze to enhance embedded system performance, with capabilities like:

• Relocatable base vector addresses for maximum memory sharing flexibility when using MicroBlaze in Zynq-7000 AP SoC devices
• New Sleep instruction enhances MicroBlaze low-power performance
• IO Module enhancements adds GPI interrupts, and programmable UART baud rate. Can be used with either MicroBlaze_MCS or full MicroBlaze
• LMB BRAM interface controller now supports multiple LMB busses
• New low latency interrupts where the controller directly supplies the interrupt vector for each individual interrupt, lowering latency response by as much as 10X depending on system design.
• Embedded designers can now add a new AXI System Cache soft-peripheral to any memory controller-based design.
