This data sheet describes the following ADSP-2100 Family processors: 3.3 V Version of ADSP-2101 Low Cost DSP with Host Interface Port Custom ROM-programmed DSPs

The following ADSP-2100 Family processors are not included in this data sheet: ADSP-2100A ADSP-2165/66 DSP Microprocessor ROM-programmed ADSP-216x processors with powerdown and larger on-chip memories (12K Program Memory ROM, 1K Program Memory RAM, 4K Data Memory RAM) Mixed-Signal DSP Processors with integrated on-chip A/D and D/A plus powerdown Speed and feature enhanced ADSP-2100 Family processor with host interface port, powerdown, and instruction set extensions for bit manipulation, multiplication, biased rounding, and global interrupt masking ADSP-21xx processor with ADSP-2171 features plus 80K bytes of on-chip RAM configured as 16K words of program memory and 16K words of data memory.

ADSP-21msp5x The ADSP-2100 Family processors are single-chip microcomputers optimized for digital signal processing (DSP) and other high speed numeric processing applications. The ADSP-21xx processors are all built upon a common core. Each processor combines the core DSP architecture--computation units, data address generators, and program sequencer--with differentiating features such as on-chip program and data memory RAM, a programmable timer, one or two serial ports, and, on the ADSP-2111, a host interface port.

Refer to the individual data sheet of each of these processors for further information. REV. B

Fabricated in a high speed, submicron, double-layer metal CMOS process, the highest-performance ADSP-21xx processors operate at 25 MHz with 40 ns instruction cycle time. Every instruction can execute in a single cycle. Fabrication in CMOS results in low power dissipation. The ADSP-2100 Family's flexible architecture and comprehensive instruction set support a high degree of parallelism. In one cycle the ADSP-21xx can perform all of the following operations:

Receive and transmit data via one or two serial ports Receive and/or transmit data via the host interface port (ADSP-2111 only)

Generate the next program address Fetch the next instruction Perform one or two data moves Update one or two data address pointers Perform a computation

The ADSP-2101, ADSP-2105, and ADSP-2115 comprise the basic set of processors of the family. Each of these three devices contains program and data memory RAM, an interval timer, and one or two serial ports. The a 3.3 volt power supply version of the it is identical to the ADSP-2101 in all other characteristics. Table I shows the features of each ADSP-21xx processor. The ADSP-2111 adds a 16-bit host interface port (HIP) to the basic set of ADSP-21xx integrated features. The host port provides a simple interface to host microprocessors or microcontrollers such as the 68000, or ISA bus.

Я тоже хотел бы с ней покувыркаться. Заплачу кучу денег. Хотя спектакль и показался достаточно убедительным, но Беккер зашел слишком .
