ADSP-2191 Descrição geral
GENERAL DESCRIPTIONThe ADSP-2191M DSP is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.The ADSP-2191M combines the ADSP-219x family base architecture (three computational units, two data address gener ators, and a program sequencer) with three serial ports, two SPI-compatible ports, one UART port, a DMA controller, three programmable timers, general-purpose Programmable Flag pins, extensive interrupt capabilities, and on-chip program and data memory spaces.The ADSP-2191M architecture is code-compatible with DSPs of the ADSP-218x family. Although the architectures are compatible, the ADSP-2191M architecture has a number of enhancements over the ADSP-218x architecture. The enhance ments to computational units, data address generators, and program sequencer make the ADSP-2191M more flexible and even easier to program.PERFORMANCE FEATURES 6.25 ns Instruction Cycle Time, for up to 160 MIPS Sustained Performance ADSP-218x Family Code Compatible with the Same Easy to Use Algebraic Syntax Single-Cycle Instruction Execution Single-Cycle Context Switch between Two Sets of Computation and Memory Instructions Instruction Cache Allows Dual Operand Fetches in Every Instruction Cycle Multifunction Instructions Pipelined Architecture Supports Efficient Code Execution Architectural Enhancements for Compiled C and C++ Code Efficiency Architectural Enhancements beyond ADSP-218x Family are Supported with Instruction Set Extensions for Added Registers, and Peripherals Flexible Power Management with User-Selectable Power-Down and Idle ModesINTEGRATION FEATURES 160 K Bytes On-Chip RAM Configured as 32K Words 24-Bit Memory RAM and 32K Words 16-Bit Memory RAM Dual-Purpose 24-Bit Memory for Both Instruction and Data Storage Independent ALU, Multiplier/Accumulator, and Barrel Shifter Computational Units with Dual 40-bit Accumulators Unified Memory Space Allows Flexible Address Generation, Using Two Independent DAG Units Powerful Program Sequencer Provides Zero-Overhead Looping and Conditional Instruction Execution Enhanced Interrupt Controller Enables Programming of Interrupt Priorities and Nesting ModesSYSTEM INTERFACE FEATURES Host Port with DMA Capability for Glueless 8- or 16-Bit Host Interface 16-Bit External Memory Interface for up to 16M Words of Addressable Memory Space Three Full-Duplex Multichannel Serial Ports, with Support for H.100 and up to 128 TDM Channels with A-Law and μ-Law Companding Optimized for Telecom munications Systems Two SPI-Compatible Ports with DMA Support UART Port with DMA Support 16 General-Purpose I/O Pins with Integrated Interrupt Support Three Programmable Interval Timers with PWM Generation, PWM Capture/Pulsewidth Measurement, and External Event Counter Capabilities Up to 11 DMA Channels Can Be Active at Any Given Time for High I/O Throughput On-Chip Boot ROM for Automatic Booting from External 8- or 16-Bit Host Device, SPI ROM, or UART with Autobaud Detection Programmable PLL Supports 1x to 32x Input Frequency Multiplication and Can Be Altered during Runtime IEEE JTAG Standard 1149.1 Test Access Port Supports On-Chip Emulation and System Debugging 2.5 V Internal Operation and 3.3 V I/O 144-Lead LQFP and 144-Ball Mini-BGA Packages
