  1. 11. Improving an FPGA Optimized Processor

    Master-uppsats, Datorteknik

    Författare :Mahdad Davari; [2011]
    Nyckelord :FPGA; Soft Microprocessor Core; IP; Cache; Exception Handling; MIPS;

    Sammanfattning : This work aims at improving an existing soft microprocessor core optimized for Xilinx Virtex®-4 FPGA. Instruction and data caches will be designed and implemented. Interrupt support will be added as well, preparing the microprocessor core to host operating systems. Thorough verification of the added modules is also emphasized in this work. LÄS MER

  3. 12. Analyzing and implementation of compression algorithms in an FPGA

    Magister-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Författare :Markus Janis; [2011]
    Nyckelord :;

    Sammanfattning : The thesis is performed at ÅF AB in Stockholm. One of the development projects needed a compression algorithm. The work has been done in two major stages. Background theory was compiled and evaluated with respect to the suitability for FPGA implementation. LÄS MER

  4. 13. A Reconfigurable FFT Architecture for Variable Length and Multi-Streaming WiMax Wireless OFDM Standards

    Master-uppsats, Elektroniksystem

    Författare :Boopal Padma Prasad; [2011]
    Nyckelord :FFT; FPGA; Reconfigurability; Wireless; OFDM; WiMax;

    Sammanfattning : This paper presents a reconfigurable FFT architecture for variable length andmultistreaming WiMax wireless standard. The architecture processes 1 streamof 2048-pt FFT, up to 2 streams of 1024-pt FFT or up to 4 streams of 512-ptFFT. The architecture consists of 11 SDF pipelined stages and radix-2 butterflyis calculated in each stage. LÄS MER

  5. 14. Adapting an FPGA-optimized  microprocessor to the MIPS32 instruction set

    Uppsats för yrkesexamina på avancerad nivå, Datorteknik

    Författare :Olof Andersson; Karl Bengtsson; [2010]
    Nyckelord :FPGA; Xilinx; Virtex-4; MicroBlaze; soft core processor; optimized; MIPS; MIPS32; Coremark;

    Sammanfattning : Nowadays, FPGAs are large enough to host entire system-on-chip designs, wherein a soft core processor is often an integral part. High performance of the processor is always desirable, so there is an interest in finding faster solutions.This report aims to describe the work and results performed by Karl Bengtson and Olof Andersson at ISY.

  7. 15. Verification and FPGA implementation of a floating point SIMD processor for MIMO processing

    Master-uppsats, Datorteknik

    Författare :Sajid Hussain; [2010]
    Nyckelord :SDR; SIMD; Xilinx; FPGA; DMA;

    Sammanfattning : The rapidly increasing capabilities of digital electronics have increased the demand of Software Defined Radio (SDR), which were not possible in the special purpose hardware. These enhanced capabilities come at the cost of time due to complex operations involved in multi-antenna wireless communications, one of those operations is complex matrix inversion. LÄS MER
