General note
This data sheet represents preliminary (x- grade) specifications for the ADSP-2188M 2.5V processor.
GENERAL DESCRIPTION
The ADSP-2188M is a single-chip microcomputer optimized for digital signal processing (DSP) and
other high speed numeric processing applications.
The ADSP-2188M 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-2188M integrates 256K bytes of on-chip memory configured as 48K words (24-bit) of
program RAM, and 56K 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-2188M is available in a 100-
pin LQFP package.
In addition, the ADSP-2188M 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-2188M operates with a 13.3 ns
instruction cycle time. Every instruction can execute in a single processor cycle.
The ADSP-2188M’s flexible architecture and comprehensive instruction set allow the processor to
perform multiple operations in parallel. In one processor cycle, the ADSP-2188M 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
This takes place while the processor continues to:
• 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
DEVELOPMENT SYSTEM
The ADSP-2100 Family Development Software, a complete set of tools for software and hardware
system development, supports the ADSP-2188M. 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.
