All the cores provide a throughput of 1 cycle/sample.

Yes, the core can be targeted to any ASIC or FPGA devices

Yes. DICOM provisions Baseline JPEG（process-1）, extended sequential DCT JPEG（process-4）, Lossless JPEG, JPEG-LS and JPEG2000 for still-image compression. CAST provides cores for all of these standards

DCT-based JPEG processes samples in MCU order.
An MCU consists of a number of 8x8 sample blocks.
The number of blocks per color plane that participate in an MCU depends on the sub-sampling format.
Raster conversion is the process of reordering samples arriving at raster scan
（i.e. line after line from top-left to bottom right）to the MCU order required for DCT-based JPEG.

If your system includes a frame buffer, then you do not need a special core for that purpose, as re-ordering of samples can be achieved by appropriate memory addressing.
If however, you need to stream data directly from your sensor to the encoder core, or from your decoder to your display system, then you need a raster conversion core.

The JPEG cores can process any MJPEG payload. The cores do not parse or construct the MJPEG container files, which are not standardized.
|
|
|
|
JPEG standards are color-blind, in the sense that the processing does not depend on color-space, and that color space is not signaled in the stream. So, the answer is that the cores support any color space with 1,3, or 4 planes.

A rate-control feature is offered with the DCT-based cores（JPEG-E, JPEG-C, JPEG-E-X, and SVE-JPEG-E）. Lossless compression does not allow for rate-control, as rate control would turn the process to lossy.
