Re: Embedded Processors/Serdes

"...Altera continues to sell Excalibur devices, this product family is
not recommended for new designs. Designs requiring embedded processors
should consider Altera's Nios® II processor.

Excalibur devices integrate a 200-MHz processor with the APEX? 20KE
FPGA architecture, balancing the price, performance, and system
integration requirements of system-on-a-programmable-chip (SOPC)
designs."

Not sure if this is just research or product development, but you could
still get Excalibur devices.
