This paper describes a processor architecture called OneChip, which combines a fixed-logic processor core with reconfigurable logic resources. Using the programmable components of this the performance of speed-critical can be improved by customizing OneChip's execution units, or flexibility can be added to the glue logic interfaces of embedded controller applications. OneChip eliminates the shortcomings of other custom compute machines by tightly integrating its reconfigurable resources into a MIPS-like processor. Speedups of close to 50 over strict software implementations on a MIPS R4400 are achievable for computing the DCT
