What is the advantage of MicroBlaze?

What is the advantage of MicroBlaze?

With the memory management unit, MicroBlaze is capable of hosting operating systems requiring hardware-based paging and protection, such as the Linux kernel. Otherwise it is limited to operating systems with a simplified protection and virtual memory model, e.g. FreeRTOS or Linux without MMU support.

What is the advantage of using the MicroBlaze soft core?

For higher performance and long-term flexibility, the MicroBlaze soft processor core provides system developers with a uniquely powerful, extensible embedded design solution. The Xilinx® MicroBlaze™ IP core is a highly configurable 32-bit microprocessor optimized for the programmable logic in Xilinx FPGAs and SoCs.

What is a soft processor core?

A soft microprocessor (also called softcore microprocessor or a soft processor) is a microprocessor core that can be wholly implemented using logic synthesis. Most systems, if they use a soft processor at all, only use a single soft processor. However, a few designers tile as many soft cores onto an FPGA as will fit.

What is Xilinx PetaLinux?

PetaLinux automates creating embedded Linux systems based on your customized hardware in Xilinx FPGAs and SoCs. PetaLinux includes U-Boot, Linux kernel, Device Tree, and Root Filesystem components.

What is MicroBlaze MCS?

MicroBlaze™ Micro Controller System (MCS) is a complete standalone processor system intended for controller applications. It is highly integrated and includes the MicroBlaze processor, local memory for program and data storage as well as a tightly coupled IO module implementing a standard set of peripherals.

What are the benefits of using a soft embedded processor in an FPGA over a hard macro implementation?

Some of the advantages of designing with soft IP cores include:

• Higher level of design reuse.
• Reduced obsolescence risk.
• Simplified design update or change.
• Increased design implementation options through design modularization.

What is soft-core and hard core?

A soft core is typically delivered in RTL, which is a hardware description language that defines logic at a higher level than a “hard core,” which is at the gate level. Occasionally, soft cores are delivered as gate-level netlists or schematics rather than RTL.

Why FPGA is faster than CPU?

This is because the FPGA can repeatedly access the memory system substantially faster than a host machine’s CPU can. FPGAs can also directly access a machine’s CPU cache along with the RAM memory.

What is the MicroBlaze CPU?

The MicroBlaze CPU is a highly customizable 32-bit RISC microprocessor, optimized for implementation in Xilinx FPGAs. Figure 1 shows a block diagram of the MicroBlaze processor core. Presets for the MicroBlaze Processor

How does MicroBlaze build the kernel?

The result of building the kernel is an elf file in arch/microblaze/boot named simpleImage. based on the dts specified. The build process for the kernel searches in the arch/microblaze/boot/dts directory for a specified device tree file and then builds the device tree into the kernel image.

What software development kits are available for the MicroBlaze processor?

System designers can leverage the Vitis™ core development kit in 2019.2, or the Eclipse-based Xilinx 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.

Can I target the MicroBlaze processor to any supported Xilinx device?

Experienced FPGA designers can use the Vivado® HL Edition design tools to target the MicroBlaze processor to any supported Xilinx device at no extra cost.
