  • Publication number: 20110178305
    Abstract: The present invention relates to a process for the preparation of threo-3,4-epoxy-2-amino-1-substituted butane derivatives represented by general Formula I which comprises reacting compound of Formula III or salt thereof with an active ester of acid of Formula IV and treating the product thereof with base. The carbon atom bonded to the radical R3 in Formula I and IV is in the (R)-, (S)- or (R,S)-configuration. The compounds of Formula I and III, particularly in their (2S,3R) configuration are useful intermediates for the preparation of atazanavir bisulfate.

  • Publication number: 20050235026
    Abstract: A multiply accumulate unit (“MAC”) that performs operations on packed integer data. In one embodiment, the MAC receives 2 32-bit data words which, depending on the specified mode of operation, each contain either four 8-bit operands, two 16-bit operands, or one 32-bit operand. Depending on the mode of operation, the MAC performs either sixteen 8×8 operations, four 16×16 operations, or one 32×32 operation. Results may be individually retrieved from registers and the corresponding accumulator cleared after the read cycle. In addition, the accumulators may be globally initialized. Two results from the 8×8 operations may be packed into a single 32-bit register. The MAC may also shift and saturate the products as required.
