As PIC16F877 has no priority of outer interruption requests,a method of using priority encoder 74LS148 to expand its outer interruption requests is proposed.
The MPEG-4video-compressing standard and PNX1300series multimedia processor are introduced,and the design of MPEG-4video-compressing PCI card based on PNX1300processor is presented. The system structure and the analysis of flow chart of coder are given also in this paper.
Communication terminal was designed with PCM, ARM-DSP, OLED and logic circuit of KEY model, and interface circuits of peripheral equipment of S3C4510B and PCM coder were expanded and simplified with ALTERA 1K30. Control signal, scanning signal of keyboard, clock signal of PCM voice coding and all sorts of data interchange channel were supplied and the serial-parallel switching of voice data of PCM was realized through inside logic circuit of 1K30.
The paper presents a wireless of the remote control keyboard made up of the single-chip computer MCS-51,the coder MC145026,F04C/ J04C wireless emission and receiving modules.
As PIC16F877 has no priority of outer interruption requests,a method of using priority encoder 74LS148 to expand its outer interruption requests is proposed.
When there are several outer interruption requests,74LS 148 sorts them according to their priorities first,the request with higher priority is then sent to the interruption input of PIC16F877.When the interruption is processed completely,PIC16F 877 waits for next interruption request.
Above all, [12:8] Harming error correction theory is mentioned in this paper. The EDAC circuit designed by VHDL can works normally at different frequency of the CPU clock such as 66MHz\50MHz\40MHz\33MHz. The EDAC function of the circuit can also be disabled by software tool.
The method of using microcontroller M68HC11 accomplished MC145026 coding function was introduced by describing the function and principle of specific coding/ decoding IC MC145026 / MC145027.This method utilized microcontroller's programmable function sufficiently .
A new packet type of control is proposed; it consists in that measurements of the sensor made with a certain frequency are stored in the digital encoder and transmitted in one packet in the network that closes the control system.
The performance of the coder-estimator sequence is compared with that of the simple feedback power control technique by evaluating their respective fade margins as in commonly done in radio system engineering.
The wavelet-based coder significantly improves the coding efficiency of the base layer compared with MPEG-4 ASP (Advanced Simple Profile) and H.26L TML9.
Convergence behavior of the proposed scheme with turbo equalization using various type of linear precoder/transformer, various interleaver size and error control coder of various constraint length is also investigated.
As the chimpanzee R-C-E-F blood group system appears to be the chimpanzee counterpart of the human Rhesus (RH) system, we have tried to determine whether chimpanzee Rh-like genes encode R-C-E-F-related proteins.
Three new types signed multiple-valued PLA’S(SMPLA’s) are proposed,Type1SMPLA realizes the signed p-valued function in the form of MAX-and-MIN of signed literalfunction. In type 2 SMPLA,the structure of PLA consists of the AND array, OR array andthe signed output encoder,and type 3 SMPLA is a two-level PLA with a combination of type2SMPLA with signed literal function and output encoder,The application in digit pipelinedadder(ADD)used in a neural network processor developed by the authors is discussed.
The design of the interfacing circuit for the intelligent position controller composed of 8031 single chip computer and the usage of single chip computer resource are emphasized. In this system, the measuring elements for speed and position feedback are implemented by optical encoder and the digital controller is implemented by single chip computer. The following error is reduced by compensating the lag error through drawing into differential feedforward term, and the acceleration / deceleration dynamic err...
