The is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications. The ADSP-2189M combines the ADSP-2100 family base architecture (three computational units, data address generators and a program sequencer) with two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O, extensive interrupt capabilities, and on-chip program and data memory. The ADSP-2189M integrates 192K bytes of on-chip memory configured as 32K words (24-bit) of program RAM and 48K words (16-bit) of data RAM. Power-down circuitry is also provided to meet the low power needs of battery operated portable equipment. The ADSP-2189M is available a 100-lead LQFP package. In addition, the ADSP-2189M supports new instructions, which include bit manipulations--bit set, bit clear, bit toggle, bit test-- new ALU constants, new multiplication instruction (x squared), biased rounding, result free ALU operations, I/O memory transfers and global interrupt masking, for increased flexibility.

Fabricated in a high speed, low power, CMOS process, the ADSP-2189M operates with 13.3 ns instruction cycle time. Every instruction can execute in a single processor cycle. The ADSP-2189M's flexible architecture and comprehensive instruction set allow the processor to perform multiple operations in parallel. In one processor cycle, the ADSP-2189M can: Generate the next program address Fetch the next instruction Perform one or two data moves Update one or two data address pointers Perform a computational operation Receive and transmit data through the two serial ports Receive and/or transmit data through the internal DMA port Receive and/or transmit data through the byte DMA port Decrement timer The EZ-ICE performs a full range of functions, including: In-target operation to 20 breakpoints Single-step or full-speed operation Registers and memory values can be examined and altered PC upload and download functions Instruction-level emulation of program booting and execution Complete assembly and disassembly of instructions C source-level debugging

This takes place while the processor continues to:

See "Designing An EZ-ICE-Compatible Target System" in the ADSP-2100 Family EZ-Tools Manual (ADSP-2181 sections) as well as the Designing an EZ-ICE compatible System section of this data sheet for the exact specifications of the EZ-ICE target board connector.

The ADSP-2100 Family Development Software, a complete set of tools for software and hardware system development, supports the ADSP-2189M. The System Builder provides a high level method for defining the architecture of systems under development. The Assembler has an algebraic syntax that is easy to program and debug. The Linker combines object files into an executable file. The Simulator provides an interactive instruction-level simulation with a reconfigurable user interface to display different portions of the hardware environment. A PROM Splitter generates PROM programmer compatible files. The C Compiler, based on the Free Software Foundation's GNU C Compiler, generates ADSP-2189M assembly source code. The source code debugger allows programs to be corrected in the C environment. The Runtime Library includes over 100 ANSI-standard mathematical and DSP-specific functions. The EZ-KIT Lite is a hardware/software kit offering a complete development environment for the entire ADSP-21xx family: an ADSP-218x-based evaluation board with PC monitor software plus Assembler, Linker, Simulator and PROM Splitter software. The ADSP-218x EZ-KIT Lite is a low cost, easy to use hardware platform on which you can quickly get started with your DSP software design. The EZ-KIT Lite includes the following features: 33 MHz ADSP-218x Full 16-bit Stereo Audio I/O with AD1847 SoundPortR Codec RS-232 Interface to PC with Windows 3.1 Control Software EZ-ICE Connector for Emulator Control DSP Demo Programs The ADSP-218x EZ-ICER Emulator aids in the hardware debugging an ADSP-2189M system. The emulator consists of hardware, host computer resident software and the target board connector. The ADSP-2189M integrates on-chip emulation support with a 14-pin ICE-Port interface. This interface provides a simpler target board connection that requires fewer mechanical clearance considerations than other ADSP-2100 Family EZ-ICEs. The ADSP-2189M device need not be removed from the target system when using the EZ-ICE, nor are any adapters needed. Due to the small footprint of the EZ-ICE connector, emulation can be supported in final board designs.

This data sheet provides a general overview of ADSP-2189M functionality. For additional information on the architecture and instruction set of the processor, refer to the ADSP-2100 Family User's Manual, Third Edition. For more information about the development tools, refer to the ADSP-2100 Family Development Tools Data Sheet.

The ADSP-2189M instruction set provides flexible data moves and multifunction (one or two data moves with a computation) instructions. Every instruction can be executed in a single processor cycle. The ADSP-2189M assembly language uses an algebraic syntax for ease of coding and readability. A comprehensive set of development tools supports program development.

Figure is an overall block diagram of the ADSP-2189M. The processor contains three independent computational units: the ALU, the multiplier/accumulator (MAC) and the shifter. The computational units process 16-bit data directly and have provisions to support multiprecision computations. The ALU performs a standard set of arithmetic and logic operations; division primitives are also supported. The MAC performs single-cycle multiply, multiply/add and multiply/subtract operations with 40 bits of accumulation. The shifter performs logical and arithmetic shifts, normalization, denormalization and derive exponent operations. The shifter can be used to efficiently implement numeric format control including multiword and block floating-point representations. -2- REV. A

The ADSP-2189M will be available a 100-lead LQFP package. In order to maintain maximum functionality and reduce package size and pin count, some serial port, programmable flag, interrupt and external bus pins have dual, multiplexed functionality. The external bus pins are configured during RESET only, while serial port pins are software configurable during program execution. Flag and interrupt functionality is retained concurrently on multiplexed pins. In cases where pin.
