Design and Implementation of 8 Bit Asynchronous Microcontroller
نویسندگان
چکیده
The synchronous microcontroller is a common processor found in many embedded system. By using asynchronous design techniques, the performance of the microcontroller is increased. Through the simulation and existing synchronous design tools in the asynchronous design flow, a “clock enabling technique” is simulated and then implemented. The asynchronous architecture includes an ALU, a decoder, a RAM, a register and a clocking element. This paper mainly deals with design of 8 bit asynchronous microcontroller simulation in Verilog using

متن کاملDesigning the Port Interface Unit for the Lutonium Asynchronous Microcontroller
The requirements, features, and implementation of the port interface unit for the Lutonium asynchronous microcontroller are covered in detail. The Lutonium is a new microcontroller that is pin-and software compatible with the Intel 8051 family of microcontrollers, and it is being designed by the Caltech Asynchronous VLSI Group. The port interface unit controls five 8-bit I/O ports, exposing the...
متن کاملA Quasi-Delay-Insensitive Microprocessor Core Implementation for Microcontrollers
Microcontrollers are widely used on simple systems; thus, how to keep them operating with high robustness and low power consumption are the two most important issues. It is widely known that asynchronous circuit is the best solution to address these two issues at the same time. However, it’s not very easy to realize asynchronous circuit and certainly very hard to model processors with asynchron...
متن کاملDesign of a RISC Microcontroller Core in 48 Hours
In this paper we present a design case study using Handel-C—a recently developed programming language for compilation of high-level programs directly into FPGA hardware. The design is an 8-bit RISC microcontroller core with 33 instructions, prescaler and a programmable timer. Handel-C was used throughout the entire design and debugging flow. The RISC microcontroller design was implemented in on...
متن کاملBit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
