Features
– Fully pipelined 24 x 24-bit parallel multiplier-accumulator (MAC)
– 56-bit parallel barrel shifter (fast shift and normalization; bit stream generation and parsing)
– Conditional ALU instructions
– 24-bit or 16-bit arithmetic support under software control
– Position independent code (PIC) support
– Addressing modes optimized for DSP applications (including immediate offsets)
– On-chip instruction cache controller
– On-chip memory-expandable hardware stack
– Nested hardware DO loops
– Fast auto-return interrupts
– Six DMA channels supporting internal and external accesses
– One-, two-, and three- dimensional transfers (including circular buffering)
– End-of-block-transfer interrupts
– Triggering from interrupt lines and all peripherals
– Software programmable PLL-based frequency synthesizer for the core clock
– Allows change of low-power divide factor (DF) without loss of lock
– Output clock with skew elimination
