dsp 223

Previously just learned single-chip computer, after a set of programming, can achieve a lot of different functions, at that time, it is felt that single-chip microcomputer is really powerful. Later came into contact with DSP, found that DSP processing digital in communication, more convenient. So I was curious to ask myself, DSP and microcontroller, what is the d

1. Introduction Robot visual servo system is an important research direction in the robot field. It originated in the early 1980s s and has made great progress with the development of computer technology, image processing technology, and control theory, some systems are in use. Visual servo is different from what we usually call machine vision. visual servo uses the principle of machine vision to automatically obtain and analyze images. From the directly obtained image processing feedback inform

The tms320c6678 is a 8-core DSP processor for the Keystone Architecture , with a frequency of up to 1.25 GHzper Corepac core, providing powerful fixed-point and floating-point arithmetic capabilities, At the same time the chip internal integration of multicore Navigator, RapidIO, Gigabit Ethernet and EDMA peripherals, due to the chip processing power, peripheral features rich, and on-chip integration of a large number of hardware accelerators, such as

Tsk Task Management Module The Tsk module provides a series of functions that access and manage task objects through Tsk_handle handles. The Dsp/bios task management module runs according to the priority of the task object and switches from one task to another by switching functions. Each task has four execution states: Run, Ready (Ready), paused (blocked), and terminated. Once a task is created, it is always in one of four states. The

Part 1: Why DSP? Advantages of DSP architecture and DSP over traditional Analog CircuitsComparison between DSP and MCU: 1. Faster processing speed 2. Built-in high-speed hardware multiplier? Enhanced multi-level pipeline (high-speed data computing capability) 3. Improved larger storage structure the haver structure has

For more information about datasheet translation, see datasheet 3.9.6. --------------------------------- 3.9.6 reset Sequence When the reset # signal is low, the clock generator enters the bypass mode. At this time, the input clock is set to clkin or x2/clkin Based on the gpio4 status. When the level of the reset # pin changes from low to high, the following events are performed in sequence. Gpio6 and gpio7 are sampled at the rising edge of the reset signal. The status of gpio6 and

This is what I encountered when using DSP to implement a function, the program requires to get a character array within the specified position of the data.1. How to declare an array:There are several ways to declare an array: CharCh[4] = {'a','b','C',};//mode 1 {} also can not fill in the data Charch2[]="Multi";//Mode 2 This way of declaring the most stable in the development of DSP engineering Cha

What is IOMath for floating-point to fixed-point operations? dsp, iomathdsp [Post Source: blog.csdn.net/lanmanck] I did not find it suitable for searching on the Internet. I will share it with you. We all know that there are few CPUs in the embedded system with floating-point operation instructions, and TI's DSP is also cheap. So what should we do if we want to increase the floating point speed during op

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
