What is MicroBlaze soft processing system?
The MicroBlaze is a soft microprocessor core designed for Xilinx field-programmable gate arrays (FPGA). As a soft-core processor, MicroBlaze is implemented entirely in the general-purpose memory and logic fabric of Xilinx FPGAs. MicroBlaze was introduced in 2002.
What is the advantage of MicroBlaze?
With the MicroBlaze processor, the designer can choose a higher-performance processor preset, change the configuration parameters of the processor, or make changes to the mix of peripherals in the system, all without changing the device package or the PCB.
What is soft CPU?
Soft Processors are microprocessors whose architecture and behaviour are fully described using a synthesizable subset of a hardware description language (HDL). Soft processors can be synthesized for any application-specific integrated circuit (ASIC) or field programmable gate array (FPGA) technology.
What is hard and soft processor?
A soft-core processor is a processor implemented using the FPGA fabric. A hard-core processor is a processor that’s actually physically implemented as a structure in the silicon. Basically, you can add a soft-core processor to a FPGA-based system after it’s already designed.
What is FPGA fabric?
FPGA fabric: The internal structure of an FPGA. The various devices that the FPGA contains, the type of interconnect, the add-on features and so on.
What is the MicroBlaze processor?
The MicroBlaze processor is a 32-bit Harvard Reduced Instruction Set Computer (RISC) architecture optimized for implementation in Xilinx FPGAs with separate 32-bit instruction and data buses running at full speed to execute programs and access data from both on-chip and external memory at the same time.
What is Xilinx MicroBlaze?
The MicroBlaze is a soft microprocessor core designed for Xilinx field-programmable gate arrays (FPGA). As a soft-core processor, MicroBlaze is implemented entirely in the general-purpose memory and logic fabric of Xilinx FPGAs. MicroBlaze was introduced in 2002.
What is the difference between MicroBlaze architecture and optional features?
The items in white are the backbone of the MicroBlaze architecture while the items shaded gray are optional features available depending on the exact needs of the target embedded application. Because MicroBlaze is a soft-core microprocessor, any optional features not used will not be implemented and will not take up any of the FPGAs resources.
How to write software to control the MicroBlaze?
Writing software to control the MicroBlaze processor must be done in C/C++ language. Using C/C++ is the preferred method by most people and is the format that the Xilinx Embedded Development Kit (EDK) software tools expect. The EDK tools have built in C/C++ compilers to generate the necessary machine code for the MicroBlaze processor.
