You need a chip based on FPGA for specific uses, but you also want a fixed performance? Possible. Xilinx, a leading worldwide FPGAs, just give information about its forthcoming chips. Family Zynq-7000, which will offer different types of FPGA interconnect - with the possibility of integrating PCI Express - Xilinx integrate what called a PPE, aka Extensible Processing Platform.
The idea is simple: the integration of ARM SoC in FPGA with an ARM CPU, a memory controller and all that is needed to launch applications ARM. The advantage is obvious: use a recent ARM chip for controlling a base system and perform simple calculations while deporting certain uses on the FPGA.
Xilinx uses a CPU type Cortex A9, the current standard, with two cores and an L2 cache shared (only) 512 KB - when the norm is 1 MB -. Good news, an FPU is included, as the NEON SIMD media instructions. Indeed, both units are optional and if the FPU is almost always present, it is not the case NEON units.
Family Zynq-7000 will be etched into 28 nm and the frequency of the CPU cores is not known, although initial reports speak of 800 MHz.
