MIPS 24KEc

MIPS 24KEc / MIPS 24KEf
A distinguishing characteristic of the 24KE family is the inclusion of the MIPS DSP
 * Application Specific Extension (ASE).

The MIPS DSP ASE provides support for a number of powerful data processing operations.

It includes instructions for executing fractional arithmetic (Q15/Q31) and for saturating arithmetic.

Additionally, for smaller data sizes, SIMD operations are supported, allowing 2x16b
 * or 4x8b operations to occur simultaneously.

Another feature of the ASE is the inclusion of additional HI/LO accumulator registers
 * to improve the parallelization of independent accumulation routines.

Variants

 * MIPS 24KEc is a 32-bit RISC core for high performance applications.
 * MIPS 24KEc Pro core offers the CorExtend capability.
 * (CP0 Status Reg, Bit 17 set for CorExtend block)


 * MIPS 24KEf core adds an IEEE-754 compliant floating point unit.
 * (CP0 Status Reg, Bit 29 set for Floating Point Unit)


 * MIPS 24KEf Pro core has both the floating point
 * unit and the CorExtend capability.

ERRATA
MIPS 24KEc share same erratas with MIPS 24K only with some version offset.
