FPGA composition, working principle, and development process Note: The following description is based on the FPGA chip of the Altera series. It is the first time to learn FPGA. Some of the content is summarized by reference to some documents, and there are still few personal analyses and insights. 1.

Today's web sites only provide user interfaces for browsers, and the next generation of programmable web sites directly link enterprises, applications, services, and devices to each other. These programmable web sites will not only be passively a

Regbank has 17 programmable Register Groups and 256x16 color palette memory, which can be use

register into the stack, Open interrupt: aims to implement interrupt nesting. Use the instruction STI. 4) return of Interruption It is completed by the instruction iret returned by the interruption. Before that, use the pop command to restore the stored field information. PIC 1. Concept The programmable interrupt control (PIC) programmable interrupt controller is generally an interrupt control system consi

hardware and directly sent to the interrupt controller, such as 8259A). Then, the interrupt controller sends a signal to the CPU, after the CPU detects the signal, it interrupts the current work and then processes the interruption. Then, the processor will notify the operating system that an interruption has occurred, so that the operating system will handle the interruption as appropriate. Now let's take a look at the interrupt controller. There are two common interrupt controllers:

? Vertex Shader and Fragment Shader are programmable pipelines. ? Vertex array/buffer objects: vertex data source. The vertex input for the rendering pipeline is then rendered. Using buffer objects is usually more efficient. In today's demo sample, the simplicity is the case. The Vertex Array is used.? Vertex Shader: vertex shader implements the operation of vertices in a programmable way, such as coo

flexible, and there are still confidentiality issues. So there is also a rom called fusible link. This rom uses a fusing link internally. device manufacturers can use high voltage to write data. After the data is written, some internal connections are fused, and the data is permanently kept inside, it is the same as the mask Rom. This one-time writing Rom is not very common.

Then, these triangles are converted from a fixed-function grating to individual fragment displayed on the screen )". Before the screen is displayed, each fragment uses a programmable Fragment Processor to calculate the final color value. Figure 1: simple Bro

While we may need to write more code, the benefits are high flexibility and, more importantly, we can control the implementation details of the renderi

rendering capabilities of 3D accelerator cards.4.ROM IntroductionROM is the abbreviation of Read only memory and is a semiconductor memory, characterized by the inability to change or delete data once it is stored. It is usually used in electronic or computer systems that do not require frequent changes to the data and will not disappear due to power off. Solid-State semiconductor memory that can read only the data stored in advance. ROM storage data, usually loaded into the machine prior to wr

hardware and sent directly to the interrupt controller (such as 8259A) and then signaled to the CPU by the interrupt controller, and the CPU detects the signal and interrupts the current work in turn to handle the interrupt. The processor then notifies the operating system that an interrupt has been generated so that the operating system handles the interrupt appropriately. Now take a look at the interrupt controller, there are two common interrupt controllers:

I. Overview Objective Kernel How to manage hardware devices: polling, interrupts. Interrupt efficiency is high and the response is faster than polling because it takes advantage of the ' interrupt signal cycle polling ' that is done before the hardware itself executes the instruction. Classification Interrupts are divided into synchronous (synchronous) and asynchronous (asynchronous).Synchronization is also known as an exception, generated by a CPU instruction error,
