This paper presents the design of high performance co-processor used to calculate the posterior probabilities for the embedded speech recognition of CHMM (Continuous Hidden Markov Model) with the MPIE (Maximum Probability Increase Estimation) algorithm to finish the most computation intensive operations in the speech recognition flow. The design of the co-processor is verified on Xilinx FPGA platform...
In order to detect the target position real-timely,a real time target detecting system based on tms320F2812 DSP and Spartan3-SC3S400 FPGA is designed.The design,hardware structure,a target detecting method and software char flow of FPGA and DSP are presented.The system is tested by a 1K×1K image,the processing time is 1.3ms, experiments results show that the method is feasible,the simple design and...
A hardware/software co-simulator has been developed for a video processing SOC. The simulator is composed of a PC and a FPGA board. The simulator realizes seamless connection between software on a PC and hardware circuits in a FPGA chip. Therefore, partial VLSI design is possible within the software. As modification on both software system and FPGA circuits are easy and as the simulation speed is...
