improve algorithm performance: the highest performance achieved by IDCT, motion compensation, and other algorithms is achieved.(2) reduce the read/write speed of the off-chip memory: Because the DSP's read/write speed on the off-chip memory is relatively slow, a DMA channel must be established between the internal and external memory to store decoded frame data, the Macro Block to be decoded is then transmitted to the internal memory through the DMA channel for high-speed processing.(3) Optimiz

Why FFT is required The first question is why it is necessary to create an FFT, simply speaking, for speed. We acknowledge that DFT is very useful, but we find that his speed is not very fast, 1D DFT primitive algorithm time complexity is O (n^2), this can be observed by the formula, for 2D DFT its time complexity is O (n^4), this speed is really difficult t

In recent years, the pattern recognition technology has become more and more widely used in access control, security and finance. A typical fingerprint recognition system is composed of a fingerprint sensor and a DSP processor. Fingerprint sensor acquisition fingerprint image, DSP processor real-time implementation of fingerprint recognition algorithm. At the same time, the usual fingerprint identification

Directio:The SRIo directio transfer class is similar to a memcopy transfer between two SRIo devices. one of the devices is the master that initiates the transfer. the second deviceis the slave that responds to the masters requests. the slave device application normallydoes not become aware of the access (the accessed salve DSP does not know the access initiated by the master DSP through SRIo ). the master m

and cost and improving reliability. Currently, embedded microcontroller is the most popular among all types of embedded processors in terms of product variety and quantity, and many of the above advantages determine that microcontroller is the mainstream of embedded system applications. The on-chip peripheral resources of the microcontroller are generally rich and suitable for control. Therefore, it is called the microcontroller. Generally, embedded microprocessor can be divided into general an

1. DSP6000 power-on sequence Problems DSP is indeed a freak. Two common problems are: (1) unable to connect to the CCS development environment; (2) burning chips. I am using TMS320C6713 now. The following experiences are based on DSP6000. Other series may be different. It seems that the performance of the chip has changed, and the chip has never been burned. However, CCS still often cannot be connected. Some of the reasons are related to the stability

-based HDL design as a reference, we will compare the comprehensive functions of the network table to see if they have the same functional equivalence. This is done to ensure that the circuit function described in the original HDL is not changed in the logical synthesis process. The form verification tool has the formality of Synopsys. The front-end design process is currently written here. In terms of design, the result of the front-end design is to obtain the gate-level network Table circuit
