Although modern FPGAs have a performance potential of a 1 GHz clock frequency - with both clock networks and embedded blocks such as memories and DSP Blocks capable of these clock rates - user implementations approaching this speed are rarely realized in practice. This is especially true of complex designs such as soft processors. In this work we implement a soft GPGPU which exceeds 950 MHz in an Altera Agilex-7 FPGA. The architecture is a 32-bit fixed point Single Instruction, Multiple Thread (SIMT) design, with parameterized thread and register spaces. Up to 4096 threads and 64K registers can be specified by the user. In one example, a processor with 16K registers and a 16KB shared memory required approximately 7K ALMs, 99 M20K memories, and 32 DSP Blocks.
