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

If a function is frequently called many times, we should start with the details. Sometimes we have no idea about the logic of the Code itself. These details can often bring us unexpected results. A type modifier is one of them. constKeywords do not need to be said, but we can often ignore them, so try to develop a habit: when designing a function parameter or declaring a variable (either local or global, subconsciously consider whether we can design this variable as unchangeable. NOTE: If it i

should I do to avoid errors?2. In the description of O3, "various cyclic optimizations have been executed". How can we optimize various cyclic optimizations? Under what conditions? What have been optimized?3. "various file-level properties are also used to improve performance". What does a file-level nature mean? Why does it improve performance? O3 is the largest optimization level, especially for loop attempts to carry out software flow. After optimization, some infrequently used intermediate

DSP中cmd文件 CMD 的专业名称叫链接器配置文件，是存放链接器的配置信息的，我们简称为命令文件，其中比较关键的就是MEMORY和SECTIONS两个伪指令的使用。 1、命令文件的组成 命令文件的开头部分是要链接的各个子目标文件的名字，这样链接器就可以根据子目标文件名，将相应的目标文件链接成一个文件；接下来就是链接器的操作指令，这些指令用来配置链接器，接下来就是MEMORY和SECTIONS两个伪指令的相关语句，必须大写。 CMD分配ROM和RAM空间,告诉链接程序怎样计算地址和分配空间。所以不同的芯片就有不同大小的ROM和RAM，存放用户程序的地方也不尽相同。所以要根据芯片进行修改，分为 MEMORY和SECTIONS两个部分。 MEMORY：用来指定芯片的ROM和RAM的大小和划分出几个区间。PAGE 0对应ROM， PAGE 1对应RAM。PAGE 里包含的区间名字与其后面的参数反映了该区间的起始地址和长度。（描述系统硬件资源） MEMORY { PAGE 0: VECS: ori

Excerpt from the Open DSP Universal GpioThere are 16 PF interfaces on the adsp-bf53x processor, which is the usual IO interface, which can be used as an external interrupt interface for each PF interface through a register configuration.The IO of the Blackfin processor is different from the MCU, the interface must be i

"Linux Development" "DSP development" using CCS6.1 to generate out files while generating bin files Try to install on Windows CCS6.1 Development am4378-linux application, this thought is OK, the result tried various methods, out file and bin file format can not be executed, the output is the binary file format is incorrect, presumably may also need to Linux host Linux installation CCS6.1 and then you can come back. The following summary is to gene

First, the chip is divided into chip-level and system-level Chip level is, just a chip, such as 51 single-chip microcomputer, you can write a program, download and follow the program to run, before and after the program System level is, can run operating system, such as ARM,SOC, have RAM and ROM Cpu: Computers should understand that the central processing Unit, computer computing core and control core, all of the following chips contain CPU, chip-level MPU: microprocessor, including CPU on

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

understood as in addition to single-chip microcomputer, DSP, FPGA and the like to call out the class of IC, the rest is ASIC. The original microcontroller is not an ASIC. For example, many manufacturers provide the design of the ASIC Gate array, but the above lead layer design can be defined according to customer design to achieve custom logic, this kind of ASIC refers to the main generation.FPGA is a programmable array, the use of a lookup table str
