GENERAL DESCRIPTION
The GPCE001A, a 16-bit architecture product, equips the newest 16-bit microprocessor, μ’nSP™ ISA 1.3 developed by Sunplus Technology. This high processing speed ensures the μ’nSP™ ISA 1.3 is capable of handling sophisticated digital signal processes (DSP) easily and rapidly. Therefore, the GPCE001A is especially targeted to the areas of DSP and Speech/Audio encode/decode. The wide range of CPU speed, from 0.1875MHz to 48MHz, makes the GPCE001A easily to be applied in varieties of applications.
