Book Description
Foating point operations are hard to implement on reconfigurable devices because of their complexity of their algorithms. On the other hand, many scientific problems require floating point arithmetic with high level of accuracy in their calculations. Therefore VHDL programming for IEEE single precision floating point multiplier module have been explored. Various parameters i.e. combinational delay (Latency), chip area (number of slices used), modeling formats, memory usage etc have been analyzed while implementing the floating point multiplier on reconfigurable hardware. Analyzing the various parameters will provide with the information that Vertex4 will consume less chip Area i.e. 663 with reduced latency i.e. 49.906 ns as compared with the other FPGAs i.e. Spartan 2, Spartan 2E, Spartan 3, Spartan 3E, Virtex, Virtex 2, Virtex 2P, and Virtex E. Floating point multiplication is a most widely used operation in DSP/Math processors, robots, air traffic controller, digital computers. Because of its vast areas of application, the main emphasis is on the implementing it effectively such that it uses less combinational delay with high Speed.

Book Description
The objective of this research is to design an efficient and flexible implementation of parallel matrix multiplication for FPGA devices by analyzing the computation and studying its design space. In order to adapt to the FPGA platform, the design employs blocking and parallelization. Blocked matrix multiplication enables processing arbitrarily large matrices using limited memory capacity, and reduces the bandwidth requirements across the device boundaries by reusing available elements. Exploiting the inherent parallelism in the matrix multiplication computation improves the performance and utilizes the available reconfigurable FPGA resources. The design is constructed by identifying the main design decisions and evaluating the alternatives for each one. The considered design decisions include the scheduling of block transfers, the scheduling of arithmetic operations in a block multiplication, the extent to which the parallelism is exploited, determining the block sizes and shapes, and the use of double buffers for storing matrix blocks. The choices offered by each decision are evaluated analytically in terms of their performance and utilization of FPGA resources. Based on this analysis, a detailed, flexible design that accommodates various alternative design choices is described. The design is optimized for matrices of floating-point elements, and for the FPGA target platform. Prior work is analyzed based on the considered design choices in order to identify the similarities and the differences. The proposed design is implemented using the VHDL hardware description language. The implementation is used to verify the correctness of the design and to confirm the analysis of the design decisions. Correctness is verified both by simulation using the ModelSim logic simulator, and in hardware through compiling the implementation using the Altera Quartus II CAD software and testing it on the Altera DE4 board, featuring a Stratix IV EP4SGX530C2 FPGA device. The implementation supports a range of parameters to facilitate the experimental evaluation of design choices. Experimental results show that the design scales linearly with respect to the consumed resources. Although increasing the system size reduces the maximum operating frequency, it also increases the parallelism, resulting in a higher performance. For instance, with 8 floating-point arithmetic units, the system runs at 320 MHz, which corresponds to a performance of 4 GFLOPS, whereas with 64 arithmetic units, it runs at 160 MHz, which corresponds to a performance of 16 GFLOPS. It is also shown that using a transfer schedule based on inner products reduces the transfer time by up to 50% compared to other schedules. Although using square blocks minimizes the number of required block multiplications, other non-square blocks minimize the transfer time, resulting in better total times.

Book Description
Here is an extremely useful book that provides insight into a number of different flavors of processor architectures and their design, software tool generation, implementation, and verification. After a brief introduction to processor architectures and how processor designers have sometimes failed to deliver what was expected, the authors introduce a generic flow for embedded on-chip processor design and start to explore the vast design space of on-chip processing. The authors cover a number of different types of processor core.
