[packer] Revise the implementation Previous prim_packer focused on to reduce register FF usage. On the side effect, it creates the timing path from valid_i --> ready_o, ready_i --> ready_o, and valid_i --> valid_o. Now the ready_o and valid_i is computed based on the current storage condition, which results in the valid_o asserting at the next cycle of valid_i earliest. Current implementation also doesn't maximize the storage utilization when mask_i is not full 1. Signed-off-by: Eunchan Kim <eunchan@opentitan.org>
OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
