DSP56321T Features

High-Performance DSP56300 Core

? 220/240 million multiply-accumulates per second (MMACS) (440/480 MMACS using the EFCOP in

filtering applications) with a 220/240 MHz clock at 1.6 V core and 3.3 V I/O and a junction

temperature range of 0–85°C

? 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)
