Abstract
Performing complex computations on data coming from fast acquisition processes can be achieved by means of a μP based architecture. While μP controls acquisition processes, a bit-slice ALU performs computation on data coming. Two different architectures are then presented. The former employs the bit-slice ALU with its own microcontroller; the latter considers the bit-slice ALU as an external support to the μP's ALU. An application involving voice signal compression is also presented. Compression is achieved by means of Walsh-Hadamard transform (WHT). A comparison between WHT and linear predictive coding is also presented.
