TMS320C62x
Evaluation Module (EVM)

Key Features

Features of the kit include:

The 'C62x board features the world's most powerful fixed-point DSP - the TMS320C6201. Using TI's revolutionary VelociTI(tm) advanced Very Long Instruction Word (VLIW) DSP architecture, the device represents breakthrough technology that enables multichannel, multifunction and advanced applications such as:

• Pooled modems
• Wireless base stations
• Remote access servers (RAS)
• Digital subscriber loop (xDSL) systems
• Cable modems
• Multichannel telephony systems

For these complex applications, the 'C6201 offers the ability to replace multiple current generation DSPs and slash system costs in half.

The full-sized EVM board is designed to be used in a PCI expansion slot. It can be used on the tabletop with an external power supply and XDS510 or XDS510WS emulator, which are not included in the kit. Functionally, the board allows high-speed verification of 'C62x code with the included C source debugger. The EVM board features a PCI interface, SBSRAM and SDRAM, a 16-bit audio codec and embedded JTAG emulation support. Connectors on the EVM board provide a DSP external memory interface (EMIF) and peripheral signals that enable it to be expanded with custom or third-party daughterboards.

In addition to providing a reference for interfacing the 'C6201 to various types of memories and peripherals, the design also addresses power, clock, JTAG and PCI controller interfaces.

EVM Hardware

The EVM hardware is divided into 12 different sections:

• C6201 DSP - The 'C62x EVM is based on the 'C62x DSP family, which operates up to 1600 MIPS with a CPU clock rate of 200 MHz. The EVM board uses a 167 MHz version of the 'C62x CPU.
• DSP clock - The EVM has two different onboard clock sources (33.25 MHz and 40 MHz) and two clock modes (multiply-by-1 and multiply-by-4), enabling the DSP to operate at four different clock rates.
• External memory - The 'C62x EVM provides one bank of 64K x 32, 133-MHz SBSRAM and two banks of 1M x 32, 100-MHz SDRAM. Additional asynchronous memory can be added with a daughterboard using the expansion memory interface. All external memory devices are byte-addressable.
• Expansion interfaces - The 'C62x EVM has external memory interface and external peripheral interface connectors that enable the use of custom or third-party daughterboards.
• PCI interface - The 'C62x EVM includes a PCI Local Bus Revision 2.1-compliant interface that enables host access to the onboard JTAG controller, DSP host port interface (HPI) and board status/control registers.
• JTAG emulation - JTAG emulation support is provided using an onboard test bus controller (TBS) as well as a header to support an external XDS510 emulator.
• Programmable logic - The 'C62x EVM's CPLD provides the board's glue logic and control/status registers.
• Audio interface - The EVM includes a CD-quality, 16-bit audio interface with stereo microphone and line-level inputs and a stereo line-level output.
• Power supplies - The EVM uses voltage regulators to provide 1.8 V or 2.5 V for the DSP core; 3.3 V for the 'C6201 I/O memories, CPLD and buggers; and 5 V for audio components.
• Voltage supervision and reset control - The EVM uses a voltage supervisor to monitor the board's voltages and provide a board reset signal.
• LED indicators - Three LED indicators are provided -- one green LED to indicate that power is on, and two LEDs for user-defined status.
• User options - The EVM supports user-defined control via 12 onboard DIP switches or with direct control by host software via the PCI bus.
