The GIFT-64-128 block cipher encryption is implemented in MIPS assembly language. The program is assembled and simulated using the QtSPIM simu-lator and produces functionally correct results. This implementation requires 22,764 clock cycles per 64-bit block encryption, as well as 1,296 bytes of code, and 192 bytes of data memory. The major functional units of the im-plementation are analyzed in terms of cycle count and bytes of code.
