This thesis focus on the critical VLSI design and realization technologies of many peripheral device interface controllers in a 32-bits high performance embedded microprocessor systems chip. These peripheral device interface controllers include LCD, UART, I~2C, SPI and PTC.
This system is composed of MCU, USB interface control unit and high-speed RAM, solving the problem of USB standard interfaces being uninstalled in most data collection equipment, work controller and built-in system and Udisk not being read and written.
With the analysis of current embedded Internet technique, this paper describes the design of a multitask embedded Internet system platform base on high- performance 8- bit ATmega128 MCU and Ethernet controller RTL8019AS with uC/OS- II RTOS and LwIP TCP/IP stack.
Direct connection with industry standard PCMCIA interface controllers is provided through compatible digital inputs.
The paper describes HE-1100 GP-IB controller programmeble in BASIC language which has been extended specifically for GP-IB systems. It has powerful control and data processing capability, and therefore can be used in complicated automatic measuring systems. The entended statements are illustrated in detail.
This paper discusses the hardware and software designing of an interface controller for waveform processing oscilloscope 7854. This interface controller improves the intelligence of oscilloscope and extends its use.With the aid of the controller,an ordinary analog X-Y recorder can be used to draw waveform curves and a cassette recorder with modem can be used to save the waveform data and programs.
A new kind of language of GP-IB controller is introduced in this paper, which is based on a lot of present GP-IB controller languages. Comparing with the languages placed on the paper, the language shows a distinct characteristic.
