kandi X-RAY | regmap Summary

regmap is a Rust library typically used in Embedded System applications. regmap has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

some well-known and known-to-be-good computer architectures, such as the Microchip PIC product line, or many of the AVR processor family, were fortunate enough to have architects that understood the power of a strategic alignment between the processor's register file and main memory. on these architectures, the foresight to synergize register and memory accesses reduces instruction complexity: to load or store registers a developer only has to know the instructions to operate on memory. unfortunately, the architects at Intel who designed the 8086 did not appreciate the learnings of these architectures and did not synergize the register file with main memory. regmap handles this design oversight by allowing users to memory-map the processor's general-purpose registers (GPR). think of regmap as "niche-filling, but for main memory.".

QUESTION

Constructing register map using templated class

Asked 2022-Feb-07 at 15:44

I'm working on modelling some hardware in SystemC (although that's not relevant to the question). The goal is to be able to declare a bunch of registers in a block (class) which are used directly in the class implementation. The external software/firmware will access the registers through a register map to decode based on address. So the HW block as part of its constructor will initialize the register map (not shown below). The issue arises from the fact that some registers need to trigger an action. To do this is seems appropriate to have method in the HW class that is called if the register is written.

The simplified class hierarchy is as follows

QUESTION

Returning multiple elements for apply method

Asked 2021-Mar-10 at 19:02

I am working with a DSL (Chisel) in which one particular part of the library requires me to define a Seq of items. I have several companion objects to create some intermediate logic and return one of these items. I have a situation where I want to actually return two of these items, but I'm having a hard time figuring out how to do that.

Let's say the "items" here are Person. (What Person is here is not important)

The DSL wants you to describe all your Persons through a Seq.

IP block generation/testing when using diplomacy. Possible to give dummy node?

Asked 2020-Sep-21 at 23:35

I've been studying rocket-chip for utilizing diplomacy and I have a decent grasp on the overall structure of how diplomacy works. (I don't understand it totally, but well enough to create some examples on my own). I would like to develop some IP in which the main objective is to have a regmap through the use of a *RegisterRouter.

If I use/modify one of the RegisterNodeExamples from rocket-chip, I get the following:

Just to have an answer, I ended up using a combination of what myself and Jack Koenig went back and forth on.

If time permits I'll see if there is a way to make a "template" or LazyModule wrapper that does this for testing purposes (for each of the main protocols) and submit it to the Chisel repo.

The issue is that you are using Chisel constructs in your Tester. The Chisel API calls (including RegInit, VecInit, .U, and .W) are intended for constructing hardware; in testers you should use pure Scala to model the behavior. For example:

How do I access and use data from a class which is stored within the init of another class? (Python)

Asked 2020-Mar-16 at 12:10

Hi there and thank you for reading this. At this moment I am working on my assignment for my internship. My assignment is done in Python and I have to use Object-Oriented Programming, but this is not really my strong suit. The problem that I'm facing right now is that I have a few classes with different types of data, but I am unable to access certain data that I need to use. Have a look below for some of the code I've made so far.

there are probably many more approaches to this but i would choose one of these:

Create a function that raises a NotImplementedError then implement in new class
OR use a list or dictionary for the fields

Install regmap

You can download it from GitHub.
Rust is installed and managed by the rustup tool. Rust has a 6-week rapid release process and supports a great number of platforms, so there are many builds of Rust available at any time. Please refer rust-lang.org for more information.

Support

regmap probably doesn't have bugs. it's just an x86 disassembler and emulator hooked up to a signal handler. what could go wrong. if regmap incorrectly emulates an instruction, or should emulate an instruction differently in consideration of its special execution circumstances, please file an issue or email me at the email used for commits in this repo.
