Composite intrinsics are constructed from a sequence of specific
or generic intrinsics.
All of the composite intrinsics are prefixed by the string
spu_.
Table 1 lists the composite intrinsics.
Table 1. Composite SPU intrinsics| Intrinsic |
Description |

| spu_mfcdma64(ls, eahi, ealow, size, tagid, cmd) |
Initiate DMA to or from 64-bit effective address |
| spu_mfcstat(type) |
Read MFC tag status |
