The e500 implements the following instructions:
Freescale Semiconductor
•
•
The embedded category instruction set for 32-bit implementations. This is composed primarily of
the user-level instructions defined by the Power Architecture user instruction set architecture
(UISA). The e500 does not include floating-point instructions that require floating-point registers
(FPRs), load string, or store string instructions.
The e500 supports the following instructions:
— Integer select. Now part of the base category. Consists of the Integer Select instruction (isel),
— Performance monitor.
— Cache locking. Consists of the instructions described in
— Machine check. Defines the Return from Machine Check Interrupt instruction (rfmci).
— SPE vector instructions. Vector instructions are defined that view the 64-bit GPRs as composed
— The embedded floating-point categories provide scalar and vector floating-point instructions.

which functions as an if
comparison to a CR bit. This instruction eliminates conditional branches, decreases latency,
and reduces the code footprint.
of a vector of two 32-bit elements (some instructions also read or write 16-bit elements). Some
scalar instructions produce a 64-bit scalar result.
Scalar single-precision floating-point instructions use only the lower 32 bits of the GPRs;
double-precision operands (e500v2 only) use all 64 bits.
