Because of the high increase in the volume of data used in designs and the large data dependencies in complex computations, researchers are motivated to highlight the need for a shift from the software based implementation of numerical integration to hardware-based FPGAs implementations that are much quicker, more efficient, and more reliable. keywords: algorithm; fpga; gate; hardware; implementation; integrals; integration; issn; method; numerical; order; parallel; www.azojete.com.ng cache: azojete-623.pdf plain text: azojete-623.txt item: #387 of 606 id: azojete-625 author: Hassan, A. ; Audu, A.
