This project introduces SpecRV, a lightweight yet powerful speculative branch prediction engine tailored specifically for RV32I 5-stage in-order pipelined processors. Built around the well-known ...

The previous installment in this series took us from the rise of the PowerPC line into the line's heyday as a leader in the RISC workstation market. During the reign of the PowerPC 600 series, Apple ...

This chapter focuses on perhaps the most important characteristic of an ISA (Instruction Set Architecture), which is a processor's instruction set. It defines and proposes how to classify instructions ...

Abstract: Instruction cache misses stall the fetch stage of the processor pipeline and hence affect instruction supply to the processor. Instruction prefetching has been proposed as a mechanism to ...

A fully custom 14-bit microprocessor implemented in VHDL and deployed on FPGA hardware. This project demonstrates the complete design cycle: from basic simulation models to a fully integrated ...

A technical paper titled “Constable: Improving Performance and Power Efficiency by Safely Eliminating Load Instruction Execution” was published by researchers at ETH Zürich and Intel Corporation. This ...
