The CPU in the loongson 1b SoC is called GS232.
Here is some active chips and it's core:

NAME              CPU       Core(s)
The loongson 3 series/server & desktop
  3A3000/3B3000     GS464E    64bit x4
  3A2000/3B2000     GS464E    64bit x4
  3B1500            GS464     64bit x8
  3A1000            GS464     64bit x4

The loongson 2 series/low power
  2K1000            GS264     64bit x2
  2F                GS464     64bit x1
  2H                GS464     64bit x1

The loongson 1 series/embeded
  1C101             GS132R    32bit ?
  1D                GS132     32bit ?
  1C                GS232     32bit x1
  1B                GS232     32bit x1
  1A                GS232     32bit x1
