Octal-TMS320C6678 DSP PCI-E FL Card contains very delicate integrated circuit chips.

In order to protect Octal-TMS320C6678 DSP PCI-E FL Card from static electricity, you should

follow some precautions whenever you work on your computer.

1. Turn off your computer and unplug power supply.

2. Use a grounded wrist strap before handling computer components. If you do not have one,

touch both of your hands to a safely grounded object or to a metal object, such as the power

supply case.

3. Plug in ATX power connector (CN6) first before turn on your computer. Some voltage’s

power source of octal card comes from 6-pin ATX power connector.

detailed number, it is summarized in the following table (Table1.DSPC-8682 Power Budget).

� VCC12 load= 12.3 A.

� VCC3.3 load=1.351 A

� Total power consumption (for EE Design) ~ 152.06W.

� Total power consumption (for Thermal Design) ~ 106.639W.

� Power budget table please refer to below.

2.5 Platform Clock

The DSPC-8682 clocks are generated by the clock synthesizers, crystals and oscillators. Introductions

for each clock are described as below.

CDCE62005: It’s a Low-Jitter clock generator with 25.0MHz crystal. It’s programmed to provide

166.66MHZ, 250MHZ and 100MHz with LVDS level for the DSP reference clocks.

ICS853S12I: It’s a PCI-E GEN3 clock buffer and provides nine reference clocks to the PCI-E switch and

support PCI-E clock for DSP.

IDT_83PN156DKI: It’s a programmable LVPECL oscillator generator with 25.0MHz crystal. It offer

156.25MHz by LVPECL level and transfer to CML level for SRIO switch by divider resistor.

CDCLVD110A: It’s a 1:10 LVDS clock buffer. There are four clock buffers which fan out 166.66MHZ,

250MHZ and 100MHz to each DSP for the reference clocks of core, DDR3, HyperLink and SRIO/SGMII

interfaces.

2.6 Reset Block Diagram

DSPC-8682 reset mechanism is shown in Figure 9. DSPC-8682 Reset Block Diagram with below

description of the reset sequence on DSPC-8682.

� The FPGA on the card will do the power-on sequence and make all power rails on the card

be ready.

� The FPGA waits for the PWROK on PCI-E golden finger (PCIE_GF_RST#) asserted.

� After PCI-E PWROK asserted as well as all the power on the card valid, the FPGA will

de-assert PEX8748_PCIE_PERST# of PEX8748, the PCI-E switch, 5482S_PHY_RST# of

BCM5482s, the PHY chip, CPS1616_RST# of CPS-1616, SRIO switch, and DSP[0:7]_RESET# on

eight DSP chips.

� To wait for 5mS, the FPGA de-assert the DSP_POR# to eight DSPs.

� To wait for 5mS, the FPAG de-assert the DSP_RESETFULLz to eight DSPs.

� During DSP_RESETFULLz de-asserted, the DSP straps the boot configurations on its own

GPIO pins driven by the FPAG.

� 1ms later after DSP_RESETFULLz de-asserted, the FPGA will set the GPIO pins on the FPGA

side at input, after that, the reset sequence on DSPC-8682 is completed then.

2.9 Memory (DDR3)

Four DDR3 memory devices are populated for each DSP on the DSPC-8682 PCI-E add-on card. The

RAM speed is 1333MHz while each DSP connects to four 4G bit (256M x 16) DDR3 devices via DDR

interface.

2.10 SRIO interface

For SRIO connection, It’s has two kind of topology to link. The one DSPC-8682 adopts a ring topology

to chain eight DSPs by one lane SRIO interface. One SRIO lane is connected to previous DSP while

another lane is connected to next DSP on DSPC-8682, e.g. the DSP#7 connects the DSP#0 with x1 SRIO

port and connect the DSP#6 with another x1 SRIO port. The other one topology is link to SRIO GEN2

switch IC (CPS-1616) with 1-laneX2 (Supports Up To 5G baud Per Lane) connected to each DSP.

2.11 PCI-E interface

DSPC-8682 adopts a star topology to link host platform with two-lane PCIE interface via a PCI-E Gen3

switch, PEX8748. One PCI-E Gen2 port is designed with two Lanes (supports up to 5G baud per lane)

connected to each DSP.

With PEX8748, it can support up to 12-ports PCI Express switch with 48 lanes of integrated on-chip

SerDes and provide an aggregated bandwidth of up to 768 GT/s. (8.0 GT/s/Lane x 48 SerDes x 2 (full

duplex))

Below table describes the port mapping of PEX8748 on DSPC-8682 while below figure describes the

PCI-E interconnection on DSPC-8682.

2.12 Ethernet MAC

There are two Gigabit Ethernet MACs in DSP TMS320C6678 and are connected by SGMII SERDES

interface. Therefore, the route of LAN packets is forwarded orderly by LAN port, DSP#0, DSP#1, DSP#2,

DSP#3, DSP#4, DSP#5, DSP#6 and DSP#7. DSPC-8682 adopts a ring topology to chain eight DSPs and

BCM5482S by one lane SGMII interface. One SGMII lane is connected to previous DSP while another

lane is connected to next DSP on DSPC-8682, e.g. the DSP#0 connects the DSP#1 with x1 SGMII port

and connect the DSP#2 with another x1 SGMII port.

On DSPC-8682, a daisy chain for LAN connections in implemented whereas the LAN port is connected

to DSP#0 via a PHY, BCM5482s, to provide 1000BASE-T Gigabit Ethernet feature.

With Ethernet PHY BCM5482S, it supports Ethernet 10/100/1000M bit/s with SGMII interface and

integrates triple-speed Ethernet transceiver-MAC to magnetic, including 1000BASE-T IEEE 802.3ab,

100BASE-TX IEEE802.3u and 10BASE-T IEEE 802.3.

2.13 HyperLink interface

Another high-speed interlink, named HyperLink, is implemented on DSPC-8682 to connect each two

DSPs (DSP#0 – DSP#7, DSP#1 – DSP#6, DSP#2 – DSP#5 and DSP#3 – DSP#4) as a pair, and its interface

can provide up to 50GT/s (12.5GT/s per lane) for data transactions.

This HyperLink interface on the TMS320C6678 is used to exchange data between two DSPs with low

latency for the specific process accelerations on DSPC-8682 PCIE card. There are four-lane SerDes

interface designed to operate up to 12.5Gbps per lane. The links of the HyperLink bus on

DSPC-8682 are connected of the DSP#0 and the DSP#7as well as the DSP#1 and DSP#6, DSP#2 and

DSP#5, DSP#3 and DSP#4)

4. Jumper and Switch setting

4.1 Boot mode switch

There is one 4-bit sliding switch (SW1) on the board to set the Endian, boot devices and variety of BRA

size for the DSP farm by the FPGA.

Below figure shows the position of the 4-bit sliding switch.

The settings of Jumper and switch for DSPC-8682 are described as below table.

Configuration Bit4 Bit3 Bit2 Bit1 Description

Endian Setting - - - ON Big Endian (0)

- - - OFF Little Endian (1)

Boot1 (000) ON ON ON - None Boot (for development)

Boot2 (001) ON ON OFF - I2C Boot from 0x51h SEEPROM

Boot3 (010) ON OFF ON - PCIe Boot

TBD Other states TBD

Table15: The SW1 setting table

The data format configuration, setting is as below.

SW1.bit1 (Endian): 0- Big Endian / 1- Little Endian (default)

The Boot interface of the DSP, the setting is as below.

SW1.bit[4:2]: 000- None boot,

This mode is for the purpose of the development.

SW1.bit[4:2]: 001- I2C boot,

This mode is booting DSP from 0x51h of EEPROM and branch to the PCIE bus for the second

boot (default).

SW1.bit[4:2]: 010- PCIE Boot,

This mode is booting DSP from PCIE interface.

SW1.bit[4:2]: others- reserved for future use.

The default setting of the switch (SW1) on DSPC-8682 is 0x0011b (bit[4:1]: ON, ON, OFF, OFF) for little

endian data format and EEPROM boot from 0x51h.

4.2 S-RIO port wide switch

There is one 4-bit sliding switch (SW2) on the board to set the SRIO configuration. The default routing

table was flashed on EEPROM is SRIO 2x. (It need to re-flash EEPROM if need to change the setting

from 2x to 1x.)

Below figure shows the position of the 4-bit sliding switch.

Below figure shows the sliding switch circuit and notes the quadrant configuration (QCFG) number for

use.
