通過以太網(wǎng)遠(yuǎn)程配置Nios II 處理器 應(yīng)用筆記
Firmware in embedded hardware systems is frequently updated over the Ethernet. For
embedded systems that comprise a discrete microprocessor and the devices it controls, the
firmware is the software image run by the microprocessor. When the embedded system
includes an FPGA, firmware updates include updates of the hardware image on the FPGA. If
the FPGA includes a Nios® II soft processor, you can upgrade both the Nios II processor—as
Part of the FPGA image—and the software that the Nios II processor runs, in a single remote
configuration session.
Nios II定制指令用戶指南:With the Altera Nios II embedded processor, you as the system designer can accelerate time-critical software algorithms by adding custom instructions to the Nios II processor instruction set. Using custom
instructions, you can reduce a complex sequence of standard instructions to a single instruction implemented in hardware. You can use this feature for a variety of applications, for example, to optimize software inner
loops for digital signal processing (DSP), packet header processing, and computation-intensive applications. The Nios II configuration wizard,Part of the Quartus® II software’s SOPC Builder, provides a graphical user interface (GUI) used to add up to 256 custom instructions to the Nios II processor.
The custom instruction logic connects directly to the Nios II arithmetic logic unit (ALU) as shown in Figure 1–1.
This application note provides a detailed description of the SPartan™-3 configurationarchitecture. It explains the composition of the bitstream file and how this bitstream isinterpreted by the configuration logic to program the Part. Additionally, a methodology ispresented that will guide the user through the readback process. This information can be usedfor Partial reconfiguration or Partial readback.
This application note shows how to achieve low-cost, efficient serial configuration for SPartan FPGA designs. The approachrecommended here takes advantage of unused resources in a design, thereby reducing the cost, Part count, memory size,and board space associated with the serial configuration circuitry. As a result, neither processor nor PROM needs to be fullydedicated to performing SPartan configuration.In Particular, information is provided on how the idle processing time of an on-board controller can be used to loadconfiguration data from an off-board source. As a result, it is possible to upgrade a SPartan design in the field by sending thebitstream over a network.
The standard that governs the design of avioniccomponents and systems, DO-254, is one of the mostpoorly understood but widely applicable standardsin the avionic industry. While information on thegeneral aspects of the standard is easy to obtain, thedetails of exactly how to implement the standard aresketchy. And once an entity develops a process thatachieves compliance, the details of how compliancewas achieved become Part of the intellectualproperty of that entity. This white paper focuses onthe details of developing a DO-254 compliantprocess for the design of FPGAs.
SRAM-based FPGAs are non-volatile devices. Upon powerup, They are required to be programmed from an external source. This procedure allows anyone to easily monitor the bit-stream, and clone the device. The problem then becomes how can you effectively protect your intellectual property from others in an architecture where the Part is externally programmed?
Field Programmable Gate Arrays (FPGAs) are becoming a critical Part of every system design. Many vendors offer many different architectures and processes. Which one is right for your design? How do you design one of these so that it works correctly and functions as you expect in your entire system? These are the questions that this paper sets out to answer.
