Are there microcontrollers with a frequency of 600 MHz - 1 GHz?

Are there microcontrollers with a frequency of 600 MHz - 1 GHz?
As part of the course, I'm trying to implement a circuit on the MK of an image transmitter. We get a discrete signal from some camera. Next, the image is encoded using error-correcting codes (for example, Hamming) and... That's all for now. In the future, the code should be sent to the modulator and transmitted over the communication channel, but now the task is to select a microcontroller that is directly suitable for this task, if it exists at all (it itself is very weak in electronics).

What is considered a microcontroller? If SoC with a bunch of built-in peripherals, then it's unlikely. If just a processor or DSP is suitable, then in bulk:
Cortex A7 / A8, Analog Devices BlackFin, Texas Instruments C66x

it all depends on the requirements and complexity. The first question .... where do these frequencies come from? From your head? calculations?
Usually, the project is first evaluated by looking for places that can be simplified, parallelized, etc. in various ways. Then, according to rough estimates, you can understand how many resources it (the project will take) and a crystal is already selected for this. Those. you need an analysis of the original task + analysis of the work algorithm.
I think FPGA will suit you. Firstly, you can get not bad speeds on it, while these speeds are constant, unlike MK, which can go to an interrupt, or to another branch. Read the rest of the advantages of FPGAs or SOCs for yourself (up to running linux)
My advice.
1) Start by reviewing the original specific problem
2) On a piece of paper/in your mind/in a program, you should have the architecture of your device at different levels. Those. how do the camera and your encoder interact? What is the image format? how is it framed and stored/transmitted? How to determine the presence of a signal? Do you need synchronization? for example, a frame was transmitted, do frames need to be separated from each other by sync words?
3) look at ready-made design solutions, there are even separate books
4) at what speed do you want to shoot and transfer images? Separately, there are a lot of questions, if there is still a modulator ...
And asking to choose an incomprehensible MK under it is not clear what .... as if it makes no sense.
