Nettetformat. The fixed-point arithmetic unit in FPGA and ASIC design is much more efficient than the floating point one. For example, a 32-bit fixed-point adder in FPGA Virtex 7 690t consumes 1DSP with 300MHz clock speed. In contrast, a 16-bit 4-stage -pipeline floating-point adder is constituted of 2 DSPs and 117 LUT with 219MHz working … The Pentium FDIV bug is a hardware bug affecting the floating-point unit (FPU) of the early Intel Pentium processors. Because of the bug, the processor would return incorrect binary floating point results when dividing certain pairs of high-precision numbers. The bug was discovered in 1994 by Thomas R. Nicely, a … Se mer In order to improve the speed of floating-point division calculations on the Pentium chip over the 486DX, Intel opted to replace the shift-and-subtract division algorithm with the Sweeney, Robertson, and Tocher (SRT) algorithm.
