- Linear program memory addressing up to 4M instruction words
- Linear data memory addressing up to 64 Kbytes
- 83 base instructions: mostly 1 word/1 cycle
- Two 40-bit accumulators with rounding and saturation options
- Flexible and powerful addressing modes: – Indirect – Modulo – Bit-Reversed
- Software stack
- 16 x 16 fractional/integer multiply operations
- 32/16 and 16/16 divide operations
- Single-cycle multiply and accumulate: – Accumulator write back for DSP operations – Dual data fetch
