VIRAM1 (Vector Intelligent RAM 1) is a low-power multimedia processor with embedded DRAM designed at UC Berkeley in 2002 and fabricated in 2003. It includes a scalar core and four vector computation units, called lanes. The goals of the chip, low-power media processing, require that the vector lanes have efficient integer multipliers that can work with a variety of data sizes. In this report, I describe an efficient partitionable integer multiplier that is designed to work in VIRAM1's vector computation lanes. The multiplier is capable of operating with a latency of two cycles at 200 MHz in a 1.2 V, .18 micron process at 64, 32, or 16 bit data width sizes, while consuming less than 250 mW of power. I describe and evaluate design options for different parts of the multiplier, and analyze the results of the chosen options.
