Field Programmable Gate Arrays (FPGAs) are commonly used to accelerate floating-point applications. The advancements in FPGA technology and the introduction of the RISC-V Instruction Set Architecture (ISA) have collectively enabled a number of soft-processor designs. Although researchers have extensively studied FPGA- based floating-point implementations, existing work has largely focused on standalone, and frequency-optimized data-path designs. They are not suitable for soft-processors targeting FPGAs due to the units' long latency, and soft-processors' innate frequency ceiling. Furthermore, the few existing integrated Floating Point Unit (FPU) hardware implementations targeting FPGA-based soft-processors are not IEEE 754 compliant. We present a floating-point unit for FPGA-based RISC-V soft-processors that is fully IEEE compliant and configurable. Our design focuses on maximizing runtime performance with efficient resource utilization. We allow the users to configure the FPU to four varying levels of compliance, or to select reduced precision configurations. Benchmarking against a set of real-world floating-point applications, we evaluate the FPU variants in term of resource usage, operating frequency, runtime performance, and performance efficiency. We also present trade-off analyses of two microarchitecture design choices. Our fully compliant FPU uses 5423 Look-Up Tables (LUTs), and achieves an operating frequency of 105 MHz. The key results from our work demonstrate the effect of running floating-point workloads using reduced compliance FPUs. Our experimentation shows that decreasing the Fused Multiply-Add (FMA)'s intermediate representation leads to a 25% reduction in LUT usage that translates to an average 46% increase in performance- efficiency. Additionally, disabling denormal support reduces resource utilization by 10% and improves the clock frequency by 6%, which results in a 14% higher performance efficiency, while having no impact on the result accuracy for our benchmark applications. Furthermore, we find that running applications in reduced precision can improve runtime performance by up to 75%, although applications may suffer from significant loss of precision.

Analog and mixed-signal circuit simulation often employs the use of the so-called LU decomposition method to solve a set of linear algebraic equations represented as Ax=b, where A is a square matrix. The LU method requires the factorization of A into two tri-diagonal matrices. Factorization is of order n power 3' time and dominates the execution time of the LU decomposition method. A number of approaches have been developed for reducing the execution time of LU factorization. One approach is to unroll the factorization algorithm and, considering each resulting assignment statement to be a machine operation, interpret the instruction stream. If an interpreter is implemented in a special purpose hardware engine there may be efficiencies to be gained by using a uniquely-developed floating-point unit within the hardware interpreter. This thesis documents the research in exploring alternatives in the design of a special purpose double precision floating point unit for a hardware interpreter to perform LU factorization using unrolled code. Alternatives explored were primarily looking at integer adder and multiplier units of the floating-point unit to determine the speed and area for each integer unit that were considered. A floating-point divider algorithm was also explored and studied. The result of this study for the pipelined floating-point unit gives the best performance with the Block Carry-look-ahead integer adder, Booth-2 integer multiplier and the SRT integer divider units. One of the interesting aspects of this research was heavy use of rapid prototyping. All models were implemented in VHDL to evaluate system level performance, synthesized by Synopsys to gate level, and analyzed for time and area at the logic level. Finally, chip level area and space characteristics were obtained using Xilinx place and route tools.
