Introduction

2Part Number 500-00191

Revision 2.00

1.2. Interfaces

In addition to the VME bus which provides the primary interface to the host computer,

the Monaco board features PMC, PEM, serial port, DSP~LINK3 and JTAG interfaces.

1.2.1. VME

Two VMEbus interfaces are provided on the Monaco board. The primary dataflow

interface supports VME64 master and slave modes for fast data transfer through the

SCV64 interface chip.

A secondary interface gives the VME A24 bus direct access to the Host Port Interface

(HPI) of each ‘C6x. This provides direct control and data transfer to and from the DSP

without interfering with dataflow on the Monaco’s Global Shared Bus.

1.2.2. PMC

The Spectrum Hurricane PCI bridge chip supports high-speed data transfer from an on-

board PMC site to the shared memory. The industry-standard IEEE-1386 PMC module

site allows developers to select from a wide variety of third-party modules.

1.2.3. PEM

Four independent high-speed, full-bandwidth, bi-directional, dataflow channels between

standard mezzanine boards (Processor Expansion Modules, or PEMs) and the ‘C6x

processors are supported. Application-specific interfaces, mounted to the PEM, are

available for computer telephony, digital radio as well as customer-specified interfaces.

1.2.4. Serial Ports

Two serial ports from each ‘C6x are available at each PEM site for on-board I/O

expansion. For each ‘C6x, one of the serial ports is always routed to the PEM site, the

second can be routed to either the PEM site or the VME P2 connector.

1.2.5. JTAG

The secondary VME interface allows access to the on-board JTAG Test Bus Controller

(TBC) from a host single-board computer for diagnostic purposes.
