Algo-Logic Systems, a recognized leader in providing hardware-accelerated, deterministic, real-time, ultra-low-latency solutions, announces the release of their latest PCI express (PCIe) with Direct Memory Access (DMA) Gen 3x8 solution for the Accelerated Finance and the Datacenter industries. Algo-Logic’s low latency PCIe/DMA solution rapidly transfers data between Field Programmable Gate Array (FPGA) logic, processors, and memory.
In many High Frequency Trading (HFT) systems, rapid data transfers are needed between FPGA logic and the Order Management System (OMS) software. For these frequent and short transactions, Algo-Logic’s PCIe/DMA solutions are optimal for minimizing latency. Similarly, in datacenter applications, PCIe solutions typically interface processors with network and storage devices. Algo-Logic’s PCIe solutions and Ethernet IP cores can be used in low latency in-memory database applications such as the Key-Value Search (KVS).
The Register Interface supports a low latency host to FPGA communication through memory-mapped I/O (MMIO) with write combining. The DMA Engine is specifically designed for kernel-bypass Linux applications that require high throughput and low latency. The DMA Engine functions include:
- Data transfer to implement zero-copy ring buffers memory mapped to user-space
- FPGA that advertises data arrival to the descriptor ring buffer
- Software API that polls from the descriptor ring buffer to detect data arrival, size, and location in the ring buffer
Algo-Logic’s PCIe/DMA solutions are plug-and-play. The hardware interfaces and software APIs are easy to use for software developers building low latency network streaming applications.
