[spi_device] Read Command module This commit implements Read command processing block. It recevies commands from cmdparse module and reads data from DPSRAM, then returns the data through SPI interface by sending bytes to spi_p2s module. It detects the command type and switch the line mode from SingleIO to DualIO or QuadIO if commands are Fast Read Dual, Fast Read Dual IO, Fast Read Quad, Fast Read Quad IO. For IO commands, the module accepts multi line address inputs. It also fixes lint and synthesis errors in the other modules inside SPI_DEVICE such as cmdparse, SPI-to-Parallel modules. Then, this commit instantiates cmdparse and readcmd modules in the IP top. 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.
