We selected jm6.1e reference software published by ITU-T as our optimization object, the goal is to achieve a base-line profile real-time codec algorithm. However, the jm6.1e code is complex and redundant. Therefore, you need to make major adjustments on the PC end, involving the following work: remove redundant code, standardize program structure, global and local variable adjustment and redefinition, and structure adjustment.　1. code migrationCode porting is to port the program running on the

Both Quartus and NIOS are of version 9.1. Find information on the Internet that version 9.1 supports MATLAB r2008a, but does not support r2009a. Then, on the official website, we found that only DSP Builder of 9.1 SP2 is supported. After installing the software in the sequence of MATLAB and DSP Builder, we found that our license had very few IP addresses. (When installing

In the field of embedded development, arm is a very popular microprocessor with extremely high market coverage. DSP and FPGA are used as co-processors for embedded development, assists the microprocessor to better implement product functions. What are the technical features and differences between the three? The following is a summary of this issue.Arm is a well-known enterprise in the microprocessor industry. It has designed a large number of high-pe

Definition of Segment 1. Cinit stores the initial values and constants of variables in the C program;. Const stores character constants, floating point constants, and constants declared with const in C programs;. Switch stores the switch statement in C program;. Text stores the C program code;. BSS reserves the storage space for global and static variables in the C program;. Far reserves space for global and static variables declared by far in C Programs;. Stack is a storage space reserved by th

This is actually my DSP course design, frankly speaking, a semester of the DSP course did not make me on the DSP chip to increase how much understanding, more harvest is finally know before looking like the Heavenly Book Digital signal processing is used to do what, however, this also does not have any eggs, also did not reduce my hatred of Fourier, Haha, I'm jok

When the Dsp/bios device is initialized, each bound function (Mdbinddev) that is registered to the micro-drive is invoked. Binding functions typically implement the following functions: Initializing peripherals based on configured device parameters and possible global device data, suspending the interrupt service function (ISRs), and obtaining resources such as caching, Mcbsps, Mcasps, and DMA. If the micro-drive uses multiple external devices, the

The ISP is the abbreviation for Image Signal Processor, which is the graphics signal processor. DSP is the abbreviation of digital Signal Processor, also known as the signal processor. The ISP typically handles output data from image sensors, such as AEC (AE control), AGC (Automatic gain control), AWB (auto white balance), color correction, Lens shading, Gamma correction, removal of bad points, Processing of auto Black level, auto white level and so o

The SWI module manages software interruption services. These interrupt service programs are closely related to Hwi hardware interrupt service programs. Generally, most of the daily processing functions are placed in these software interrupt service programs for management and operation. I. Overview of the SWI Module In the DSP/BIOS kernel, the threads managed and run by the system are divided into four levels: hardware interrupt service program, softw

Work Phase:The workflow is generally divided into three stages. Phase 1: Use the C language to implement the function as needed. In actual DSP Applications, many algorithms are very complex and can be directly written using assembly code. Although the optimization efficiency is very high, the implementation is very difficult, therefore, it is generally implemented in C language and then compiled and run. The program running time is tested using the pr

Design NotesFingerprint identification is used in a variety of applications, including electronic access control systems, smart cards, vehicle ignition switch controls, USB memory sticks with fingerprint-controlled access, and many other applications. The digital signal processing elements in fingerprint scanner can perform complex DSP functions such as filtering, transformation, feature extraction, matching operation and other algorithms.Fingerprint

recently by the MCU and MPU dizzy, the Internet to find some relevant information, tidy up. The CPU (central processing Unit, CPU) developed three branches, one is the DSP (digital Signal processing/processor, signal processing), the other two are MCU (Micro Control Unit, microcontroller unit) and MPU (Micro Processor Unit, microprocessor unit).MCU integrates the on-chip peripheral devices, MPU without peripheral devices (such as memory array), is a
