How to validate an application on a RISC-V processor with custom instructions, analyze the application execution, and optimize the custom instruction implementation and its documentation. A RISC-V ...

For more than three decades, modern CPUs have relied on speculative execution to keep pipelines full. When it emerged in the 1990s, speculation was hailed as a breakthrough — just as pipelining and ...

Fence instructions are a coarse-grained mechanism to enforce the order of instruction execution in an out-of-order pipeline. They are an overkill for cases when only one instruction must wait for the ...
