Titan II
Designed ByIBM

The Titan is a development board used during Bringup of the Shiva and Waternoose Engineering Sample CPUs. It also allows an IBM RISCWatch to be used to debug and test the processors.

Specifications

  • Xilinx Spartan 3 XC3S200 FPGA
  • 128KB Xilinx XCF01S JTAG PROM
  • 4 DIP Switches
  • 9 3.3V LEDs (Later versions only)
  • 50MHz 3.3V Crystal

Details

The Titan is powered off the console via the 3.3V V_MEMPORT and 1.8V V_1P8 rails. The 3.3V is also stepped down to 2.5V and 1.2V.

The 10-pin J_YETI header connects to J8C1, the CPU JTAG header, while the 12-pin J_GPUL header connects to J7G2, the Shiva JTAG header.

Different bitstreams are required for Shiva, and the various revisions of Waternoose.
