Is $readmem synthesizable in Verilog?

由 一曲冷凌霜 提交于 2019-12-01 00:48:58
问题 I am trying to implement a microcontroller on an FPGA, and I need to give it a ROM for its program. If I use $readmemb, will that be correctly synthesized to a ROM? If not, what is the standard way to do this? 回答1: I would amend George's answer to say that it depends on the synthesis tool whether or not $readmemb is synthesizable. Altera's Recommended HDL Coding Styles guide includes example 10-31 (page 10-38), which demonstrates a ROM inferred from $readmemb (reproduced below): module dual

How to override a superclass' property with more specific types?

问题 The Scenario I have a situation where a base class called AbstractRequest has a delegate property of type id <AbstractRequestDelegate> declared in the header file: @property (nonatomic, assign) id <AbstractRequestDelegate> delegate; The abstract delegate protocol contains a few required methods, and as indicated with the word 'abstract', both the AbstractRequest and the AbstractRequestDelegate are intended to be subclasses/extended. One example of this would be the subclass ConcreteRequest

Android Audio - Streaming sine-tone generator odd behaviour

由 浪子不回头ぞ 提交于 2019-11-30 07:11:32
first time poster here. I usually like to find the answer myself (be it through research or trial-and-error), but I'm stumped here. What I'm trying to do: I'm building a simple android audio synthesizer. Right now, I'm just playing a sine-tone in real time, with a slider in the UI that changes the tone's frequency as the user adjusts it. How I've built it: Basically, I have two threads - a worker thread and an output thread. The worker thread simply fills a buffer with the sine wave data every time its tick() method is called. Once the buffer is filled, it alerts the output thread that the

Sound synthesis with C#

Is there some possibility to generate sounds in C#? I mean not just beep or open and play wave-file. I mean build the signal using different kinds of waves (sin, saw, etc.) and their options (frequencies, amplitudes, etc.) Check out NAudio on codeplex. NAudio is an open source .NET audio and MIDI library, containing dozens of useful audio related classes intended to speed development of audio related utilities in .NET. It has been in development since 2001 and has grown to include a wide variety of features. While some parts of the library are relatively new and incomplete, the more mature

While I was playing and figure out how things work in https://github.com/enormego/EGOTableViewPullRefresh I found mysterious of @property and @synthesize. Here is the code I mentioned EGORefreshTableHeaderView.h @interface EGORefreshTableHeaderView : UIView { id _delegate; EGOPullRefreshState _state; UILabel *_lastUpdatedLabel; UILabel *_statusLabel; CALayer *_arrowImage; UIActivityIndicatorView *_activityView; } @property(nonatomic,assign) id <EGORefreshTableHeaderDelegate> delegate; EGORefreshTableHeaderView.m @synthesize delegate=_delegate; I have read this http://developer.apple.com

Sound generation / synthesis with python?

由 瘦欲@ 提交于 2019-11-28 03:28:29
Is it possible to get python to generate a simple sound like a sine wave? Is there a module available for this? If not, how would you go about creating your own? Also, would you need some kind of host environment for python to run in in order to play sound, or can it be achieved just from making calls from the terminal? If the answer is OS-dependent, I'm using a mac. Liam I was looking for the same thing, In the end, I wrote this code which is working fine. import math #import needed modules import pyaudio #sudo apt-get install python-pyaudio PyAudio = pyaudio.PyAudio #initialize pyaudio #See

Convert Mat to Array/Vector in OpenCV

由 房东的猫 提交于 2019-11-26 18:37:34
I am novice in OpenCV. Recently, I have troubles finding OpenCV functions to convert from Mat to Array. I researched with .ptr and .at methods available in OpenCV APIs, but I could not get proper data. I would like to have direct conversion from Mat to Array(if available, if not to Vector). I need OpenCV functions because the code has to be undergo high level synthesis in Vivado HLS. Please help. If the memory of the Mat mat is continuous (all its data is continuous), you can directly get its data to a 1D array: std::vector<uchar> array(mat.rows*mat.cols); if (mat.isContinuous()) array = mat
