General

The Deskstation Evolution Series rPC/44 is another ARC system. Based on the MIPS R4400 processor and ARC firmware it was targetting the Windows NT market.

The DeskStation system looks like many PC clones because it is based on an AT motherboard. The basic difference is the additional logic required for the R4400 bus to communicate with the EISA bus. The memory bus is only 32 bits wide, while the CPU itself has a 64-bit-wide path; therefore 512K of secondary cache is used to enhance performance.

Linux Support

For a short time rPC44 support was being worked on. It never reached any functional state. The rPC44 code has therefore been removed from Linux.
