• 200 million multiply-accumulates per second (MMACS) (400 MMACS using the EFCOP in filtering applications) with a 200 MHz clock at 1.6 V core and 3.3 V I/O
• Object code compatible with the DSP56000 core with highly parallel instruction set
• Data Arithmetic Logic Unit (Data ALU) with fully pipelined 24 × 24-bit parallel Multiplier-Accumulator (MAC), 56-bit parallel barrel shifter (fast shift and normalization; bit stream generation and parsing), conditional ALU instructions, and 24-bit or 16-bit arithmetic support under software control
• Program Control Unit (PCU) with 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, and fast auto-return interrupts
• Direct Memory Access (DMA) with six DMA channels supporting internal and external accesses; one-, two-, and three-dimensional transfers (including circular buffering); end-of-block-transfer interrupts; and triggering from interrupt lines and all peripherals
• Phase Lock Loop (PLL) allows change of low-power Divide Factor (DF) without loss of lock and output clock with skew elimination
• Hardware debugging support including On-Chip Emulation (OnCE) module, Joint Test Action Group (JTAG) Test Access Port (TAP)
