The LogiCORE™ 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 I/O module implementing a standard set of peripherals.

El tiempo de acceso a la memoria BRAM es reducido debido a que se emplean recursos específicos para su acceso. MicroBlaze hace un uso efi-ciente de los recursos disponibles en la FPGAs actuales, por lo que es posible llegar hasta frecuencias de reloj de 150 MHz [3].

However, if the program has lots of random access, then a shorter cache word will present a better solution. In the MicroBlaze, we can select 4-, 8- or 16-word line length. Data Width - This is the width of the data bus used for the BRAM. Do we want a fixed width with 32 bits or set to match the cache line size.

The communication between microblaze processors is through a FSL (Fast Simplex Link) channel; and the four processors execute an image processing application in parallel. This system can be implemented in two ways: 1. In a StepNP SystemC simulation environment. 2. On the FPGA housed in the AMIRIX AP1000.

MicroBlaze is a simple, versatile soft-core processor that can be used in Xilinx FPGA only platforms, such as the Kintex-7, to perform the functionality a full-fledged processor, or as a flexible, programmable IP. When programs are small, the ELF can sit in BRAM and the design becomes completely self contained in the FPGA.

The problem The Xilinx Microblaze soft processor, which is implemented on the FPGA’s logic fabric, is indeed a stable and fully capable processor, but its rather low clock frequency — 70-100 MHz on a Spartan-6 — makes it a problematic candidate for data capture and frame grabbing.

The memory the microblaze use to store it's program is limited to 32 bits, as far as I know. To use the larger memories you would need to connect it to an AXI port. Otherwise, Xilinx has an answer record on how to use 2 differents 64kB memory to present 128kB to the microblaze. Do you really need that much memory?.

In a MicroBlaze system, the cache is implemented in BRAM and provides much faster access than accessing off-chip memories. The memory range allocated for the cache coverage must be outside the Local Memory Bus (LMB) address range. With both the cache and LMB implemented in BRAM, it would have little performance impact to cache the LMB. .

In this wiki we will demonstrate how to create a non-maskable break (high priority interrupt) on the Microblaze using the Ext_NM_Brk port to jump directly to the interrupt handler. ... and uses an AXI Timer to generate the interrupt.There is a TCL script delivered in the Zip file below: To build, launch Vivado 2018.1, and run the command below. In typical systems containing a Microblaze the executable BRAM is populated with a bootloop that is automatically generated in Vivado based on the Microblaze BOOT_VECTOR. This bootloop ELF is then associated in Vivado. The reason for the bootloop is so the Microblaze has some valid instructions to execute once the Microblaze comes out of reset.
