The Hammerhead-PMC+ Quad ADSP-21160 PMC DSP Card

The Hammerhead-PMC+ is a new PMC DSP card featuring four 100 MHz Analog Devices ADSP-21160 SHARC™ DSPs and a 64-bit, 66 MHz PCI interface. Fully compatible with any PMC-capable carrier board, the Hammerhead-PMC+ allows designers to add DSP capabilities to their single-board computers or additional processing power to their BittWare carrier boards without taking up an extra slot. When attached to one of BittWare's PMC+ capable carrier boards, it also supports BittWare's PMC+ extensions, which include link ports, a serial TDM bus, a reset line, and interrupts.

The Hammerhead-PMC+ integrates ADSP-21160 processing power with a 64-bit 66 MHz PCI interface, expansive memory options, a variety of I/O interfaces, and BittWare's SharcFIN ASIC technology – all on a single PMC card. The board features four ADSP-21160 SHARC DSPs, each providing 600 MFLOPs of processing power for a total of 2400 MFLOPs. I/O interfaces on the board include four external link ports, a 64-bit 66 MHz PCI interface, an RS-232 port, a JTAG emulation interface, and two external serial ports. For memory options, the board supports a 64-512 MB bank of SDRAM and a 2 MB bank of Flash memory.

Providing the backbone of the Hammerhead-PMC+'s architecture is a SharcFIN ASIC. The SharcFIN ASIC provides a comprehensive set of bus interfaces and peripherals for the ADSP-21160 DSPs and provides a clean, elegant board-level implementation. It integrates a full-featured SDRAM controller, a full 64-bit 66 MHz master PCI interface, a peripheral bus that interfaces the DSPs to peripherals such as the RS-232 UART and Flash, and an extensive flag and interrupt multiplexer.

A complete set of software development tools is available to support the Hammerhead-PMC+. BittWare's DSP21k Toolkit allows users to easily develop application code and integrate the Hammerhead-PMC+ into their systems. Drivers are available for Windows 95/98/NT/2000 and Linux; a source code porting kit is also available. The board is fully compatible with Analog Devices' VisualDSP® and supports in-circuit emulation. It is also compatible with SpeedDSP™, BittWare's highly-optimized, C-callable runtime libraries, and with Sharc®LAB, BittWare's interface to MATLAB Simulink® and Real-Time Workshop®.
