Our goal is to enable FPGA Designers to design better and faster with Fast Flash Programming – no matter what FPGA devices they’re working on. We have extended the list of devices that we cover from FPGA vendors such as Intel (formerly Altera), AMD (formerly Xilinx), and Microchip (formerly Actel), and the list continues to grow!

The AAEON UP Xtreme i12 Core i7-1270PE board is unique, because, in addition to being able to debug it with JTAG using the Intel Direct Connect Interface (DCI), its CPU has support for Virtualization Technology Redirect Protection: VT-rp. VT-rp is a foundational requirement for advanced security features, specifically Hypervisor-managed Linear Address Translation (HLAT), Paging-Write (PW), and Guest-Paging Verification (GPV).

The more complex the embedded FPGA design or system image file the longer it takes to program. The longer it takes to program, the more expensive production is. This is especially true for when embedded files get larger than 10MB. Read more on how Fast Flash Programming can help to dramatically reduce programming times.
