Programmable digital controller
Over the past few decades, FPgas have become the hardware platform of choice for digital processors and high-speed data processing devices. But with the continuous improvement of computer graphics processing function, FPGA is becoming a variety of industrial control application function and performance of the ideal choice. However, due to its high price and long design cycle, its cost and design difficulty increase with the expansion of production scale. Although FPgas offer great advantages in terms of performance, there are still many design challenges that need to be addressed. This article discusses how to use FPGas to achieve application goals with specific performance, price, and design requirements. FPGA is usually a type of microcontroller, but there are a variety of programmable devices available today, most of which can be used on a PC; This article discusses common programmable devices.

Programmable devices can be implemented by hardware or software. In terms of hardware, they are implemented through the use of software, otherwise known as programming. The programmable features of hardware and software can meet different customer requirements. For example, software based on CPU or GPU is suitable for embedded systems requiring different functions. Software-wise, they can use a variety of programming tools, such as serial/parallel processing, hybrid programming of FPGas with cpus or Gpus, and embedded systems based on software stacks of Cortex-M3 processors. Programmable features of hardware and software include: dynamic bandwidth, hardware clock, interrupt frequency (interrupt), memory size), hardware counter (counter), data input and output bandwidth, etc. Software modules include: clock module, processor /GPU module, CPU/M3 module, processor clock, bus memory and driver; CPU can be programmed and modified by multiple kernel /Bootstrap (main kernel/parallel processing) modules; The communication between external interrupt and external memory can be configured to avoid any unexpected events. Also can use hardware clock, logic counter, instruction buffer and other devices to complete the programming function and the corresponding test requirements.
Since FPgas are usually composed of microcontrollers (MCU), the MCU is usually composed of programmable devices. There are usually many different types of MCU, one of the basic programmable hardware requirements is as follows: have precise control data sampling control instructions, such as sampling speed, sampling rate setting, sampling rate and sampling rate setting; With precise control commands, such as interrupt, control I/O control, etc. With perfect control logic, such as system controller, signal integrity control, etc. It has high reliability and miniaturized structure.

The following describes several typical programmable devices through two devices with low cost and high performance. This programmable device provides a wide range of options for high-performance controllers; Two typical devices are VIGHTS and ARMv812A. Both devices provide dedicated hardware resources that can be used for low-cost design, as shown in Figure 3 running analog circuit design software on Lumentum's VIGHTS devices. Both devices, developed by Altera, are cost-effective and offer a variety of hardware capabilities and software programmability. A variety of hardware resources are also provided (see Figure 4). By comparing the two devices, two typical device characteristics and operation instructions can be obtained (Table 1). These two examples are probably one of the most important feature repositories for a typical programmable device
