1.6 DSP56300 Core Functional Blocks
The functional blocks of the DSP56300 core are:
Freescale Semiconductor
100 million instructions per second (MIPS) with a 100 MHz clock at 3.0–3.6 V
Highly parallel instruction set
Data arithmetic logic unit (Data ALU)
— Fully pipelined 24 × 24-bit parallel multiplier-accumulator (MAC)
— 56-bit parallel barrel shifter (fast shift and normalization; bit stream generation and
— Conditional ALU instructions
— 24-bit or 16-bit arithmetic support under software control
Program control unit (PCU)
— Position Independent Code (PIC) support
— Addressing modes optimized for DSP applications (including immediate offsets)
— Instruction cache controller
— Internal memory-expandable hardware stack
— Nested hardware DO loops
— Fast auto-return interrupts
Direct memory access (DMA)
— 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
Phase lock loop (PLL)
— Allows change of low power Divide Factor (DF) without loss of lock
— Output clock with skew elimination
Hardware debugging support
— On-chip emulation (OnCE) module
— Joint Test Action Group (JTAG) Test Access Port (TAP)
— Address Trace mode reflects internal program RAM accesses at the external port
Reduced power dissipation
— Very low-power CMOS design
— Wait and stop low-power standby modes
— Fully-static design specified to operate down to 0 Hz (dc)
— Optimized power-management circuitry (instruction-dependent, peripheral-dependent,
Data arithmetic logic unit (ALU)
Address generation unit
