GENERAL DESCRIPTION

   The PACE1750AE is a general purpose, single chip, 16- bit CMOS microprocessor designed for high performance floating point and integer arithmetic, with extensive real time environment support. It offers a variety of data types, including bits, bytes, 16-bit and 32-bit integers, and 32-bit and 48-bit floating point numbers. It provides 13 addressing modes, including direct, indirect, indexed, based, based indexed and immediate long and short, and it can access 2 MWords of segmented memory space (64 KWords segments).
