Buffer

I am currently working on a project that need to convert some
asynchronous and digital data from a serial port of a computer into
synchronous RF data. In order to do this, I will need a buffer to
store the digital data prior to process it. The buffer need to be
larger than 1 kilobyte and has the capability to hard wire into the
serial port to prevent buffer overflow/underflow. Please let me know
where or how I can find a buffer like this. I have been looking
several electronics distrubtor such as Digikey and Jameco and I was not
able to find it. I will appreciate your help. Thank you.

 

FAIK a component like this is not an of the shelf product. You'll have to
build your own one. There have been days you'd use a stand alone UART with a
Baudrate generator, a 1kB FIFO and some glue logic. It can still be done
this way, but I doubt you to have the skills to design it. These days the
way to go is using a micro with a build-in UART, a timer/counter to generate
the correct Baudrate, over 1kB of RAM and the firmware to make it run. Alas,
it requires some skills to design this too so I guess you'll have to learn
about micros and their programming to make what you want.

This is a job for a small computer. It could be done with a largeish
microcontroller, but a single-board computer might be easier to work with.
Or could the conversion be done by the computer that is outputting the data?
