چکیده

In this report, we present a top-down VHDL modeling technique which consists of two main modeling levels: speci cation level and functional level. We modeled a RISC Processor (RP) in order to demonstrate the feasibility and e ectiveness of this methodology. All models have been simulated on a SPARC 1 workstation using the ZYCAD VHDL simulator, version 1.0a. Experimental results show feasibility of the modeling strategy and provide performance measures of RP design features.

Parallel Processors Architecture in FPGA for the Solution of Linear Equations Systems

This paper presents a parallel array of processors implemented in a Field Programmable Gate Array (FPGA) for the solution of linear equations systems. The solution is performed using the division-free Gaussian elimination method. This algorithm was implemented in integrated processors in a FPGA Spartan 3 of Xilinx. A top-down design was used. The proposed architecture can handle IEEE 754 single...

FPGA Implementation of a 64-Bit RISC Processor Using VHDL

In this paper, the Field Programmable Gate Array (FPGA) based 64-bit RISC processor with built-inself test (BIST) feature implemented using VHDL and was, in turn, verified on Xilinx ISE simulator. The VHDL code supports FPGA, System-On-Chip (SOC), and Spartan 3E kit. This paper also presents the architecture, data path and instruction set (IS) of the RISC processor. The 64-bit processors, on th...

VHDL-AMS Behavioral Modeling and Simulation of a π/4 DQPSK Transceiver System

This paper describes a methodology for top-down design, modeling, and simulation of complete π/4 DQPSK system using hardware description language VHDL-AMS. Two system implementations are considered: with and without Viterbi encoder/decoder. VHDL-AMS implementations of various RF blocks (e.g. a realistic channel model) are developed, the system is simulated, and bit error rate is evaluated in th...
