Performance Improvements For Open-Source 80386
A team working on an open-source FPGA implementation of the Intel 80386 processor has made several performance improvements by optimizing memory access and branch prediction. These changes, including early memory allocation and revised microcode decoding, resulted in a 39% performance boost in the DOOM benchmark. The project is ongoing, and while the FPGA version is not yet fully functional or as fast as the original chip, the progress highlights continued interest in retrocomputing and hardware innovation.
