The HYDRA XTREME 512K Card (HX512) completes the HYDRA system giving it a full 512K of Static RAM (SRAM) and 128K BYTE EEPROM for program storage. The interface between the HYDRA and the HX512 is made possible by a state-of-the-art Lattice ispMach 4064 Complex Programmable Logic Device (CPLD) which acts as the memory controller and "glue" logic interfacing the HYDRA and the HX512.

The CPLD is used to address the large 512K memory as well as act as a simple memory controller that is capable of auto increment and decrement functionality to help accelerate your code. With this exciting addition to your HYDRA, it literally transforms the HYDRA into a full featured 32-bit computer that can host large programs, operating systems, interpreters, compilers, and more advanced games and graphics applications.

Additionally, the Lattice CPLD can be re-programmed with a 3rd party programmer or one your build (instructions included on CD-ROM). By re-programming the CPLD, you can literally change the "personality" and behavior of the HX512 altering it to suit your needs as well as using the HX512 as low-cost CPLD development kit. The CPLD development tool is included on CD-ROM. In addition to the hardware is a complete software API suite consisting of both a SPIN based API and highly accelerated ASM API. Both APIs are well documented in the HYDRA XTREME 512K SRAM CARD Programming and User Manual that comes on the CD-ROM. Over 80 pages of illustrations, explanations, and source code will get you jump-started with the HX512!

Features:

• 512 KB of SRAM addressable via a byte wide bus and a handful of control lines
• First 64 KB of SRAM directly addressable, upper 448 KB block addressable
• Programmable post increment/decrement after reads/writes allowing for high speed block access
• SRAM can be accessed as fast as global (HUB) memory in many cases from within a COG
• Built in 128K EEPROM on board, so firmware can be loaded onto EEPROM rather than HYDRA main board
• LEDs for status and debugging uses
• CPLD is reprogrammable, includes complete instructions and designs for a DIY programmer for under $10 of parts

Kit Contents:

• HYDRA XTREME 512K SRAM Card
• PC compatible CD-ROM with drivers, source, demo & complete programming manual
