This is a very generic question, C programming on What? is there OS on the system?
C programming means a compiler, an IDE and libraries and output assembly code that will be rendered, generally speaking it is totally different to produce a binary file that will work directly on a processor, that...
how does grey code help async clock crossing
I don't understand your question however I will add a note, that might answer u, the metastability filter (two FFs usually) diminish the probability of metastability propagation, which might cause circuit failure, metastability might also cause...
UART -help
Well I can give you some guidelines, first of all of course you will put the regular two FF (metastability Filter), then some switch detection circuit, i.e. a circuit which will determine if data changed from zero to one, you logic must work at at least double the clock speed...
grey code in clock crossing domain
Guys,
if you read wrong data this doesn't mean metastability ... !
just simply according to any logic data should be sampled at some specific time (hold period) which is managed by passing the clock.
when you read data Bus Asynchronously you may get wrong...
Async to Sync
Well it depends on the data rates, Like UART, a start and stop bit is enough, you can sample the data at double the speed or more, using a technique to aviod metastability a lot of techniques out there and a technique to detect 0-1 transition.
At very high speed Async data you...
how is appalix
1-synchronizer is used to decrease the probability of metastability not to allow it!
2-One bit is not data it is a signal if you want just sample it directly you will only have a more probability that ur circuit fail or hang or read wrong data for a longer period of time
you need...
metastable clock domain crossing
ASIC_int
0101 is not a metastable state, when you read 0101 usually means that data was read on its transition state but since you read some value then you read right the problem mainly is that value that you didn't reach metastable state.
If you read data bus...
double flop synchronizer book
guys metastability is not that you read wrong data it is that your circuit might work in non descrete mode simply your FF is more or less some transistors they are designed in such a way that it will usually be saturated or switched off (on-off) however there is...
xilinx delay function
J_andr I dont say that tricks will not work and it is ok to do so and I have done this actually in some ciruits you can't get some data except with a delayed pulse" like DDR DQs" but you can't get a delayed clock this way and if your pulse route is big or it drives more...
xilinx synthesis issues
First of all I wouldn't do such a delay ever, it is inreliable and a Buf object is not routed to the global clock network and you can't use a BUFG to delay a clock, use DCM for delaying a clock
Anyway I think the problem is in the resolution you are using in the...
problems connecting to domain as clock incorrect
FIFO is used when you need to transfer data from one clock domain (clock domain at which you store data) to another clock domain, it grantees that the data will cross from that domain to the other (smoothly) if the Asynchronous FIFO is designed...
