500 MHz PulseBlasterESR QuadCore: High Speed Programmable Pulse Generator and Digital Word Generator


Ordering Information
Manuals, etc.

500 MHz PulseBlasterESR QuadCoreTM is a 500 MHz Four-Core PulseBlaster design implemented on a new series of PulseBlasterESR PCI boards. The Four-Core design uses four of SpinCore's proprietary PulseBlaster processor cores, specially designed for QuadCore operation, on a single chip. This new design allows the user to program and run independent programs on each core, in parallel, while maintaining precise timing synchronization between the cores.

All four cores are driven by the same, single clock source. They can be synchronized to start at the same time and run four unique pulse programs/sequences concurrently. At 500 MHz, the available resolution of each pulse/delay/interval is 2.0 ns (one clock cycle). The PulseBlasterESR QuadCore comes in two different models:

The internal memory model of the PulseBlasterESR QuadCore TURBO has a minimum pulse/delay/interval length of 6 clock cycles, or 12.0 ns, and the maximum pulse/delay/interval length is 2^27 clock cycles (~268.4 ms). Each core has up to 2K instructions.

The external memory model of the PulseBlasterESR QuadCore TURBO has a minimum pulse/delay/interval length of 17 clock cycles, or 34.0 ns, and the maximum pulse/delay/interval length is 2^30 clock cycles (~1.07 s). Each core has up to 2097152 instructions.
