xxxii ADSP-21368 SHARC Processor Hardware Reference
Manual Contents
The manual consists of:
• Chapter 1, “Introduction”
Provides an architectural overview of the ADSP-21367/8/9 and
ADSP-2137x SHARC processors.
• Chapter 2, “I/O Processor”
Describes ADSP-21367/8/9 and ADSP-2137x processors
input/output processor architecture and direct memory accesses
(DMA) for the peripherals that have this feature.
• Chapter 3, “External Port”
Describes the operation of the asynchronous memory interface
(AMI).
• Chapter 4, “Digital Audio/Digital Peripheral Interfaces”
Provides information about the digital applications interface (DAI)
which allows you to attach an arbitrary number and a variety of
peripherals to the ADSP-21367/8/9 and ADSP-2137x processors
while retaining high levels of compatibility.
• Chapter 5, “Serial Ports”
Describes the up to eight dual data line serial ports. Each SPORT
contains a clock, a frame sync, and two data lines that can be con-
figured as either a receiver or transmitter pair.
• Chapter 6, “Serial Peripheral Interface Ports”
Describes the operation of the SPI port. SPI devices communicate
using a master-slave relationship and can achieve high data transfer
rates because they can operate in full-duplex mode.
• Chapter 7, “Input Data Port”
Discusses the function of the input data port (IDP) which provides
a low overhead method of routing signal routing unit (SRU) sig-
nals back to the core’s memory.
