This article introduces two 32-bit Multi-Core Families that expand on Lumissil's Multiprocessor (MPU) portfolio: the X1600 and X2000. These MPUs utilize XBurst, a family of MIPS processors with (FPU) Floating Point Unit, dedicated security processor and use a System-in-Package (SIP) architecture to house memory. These features facilitate complex DSP computations, enable authentication, perform encryption/decryption and manage data storage. By integrating these features, the need for costly licenses is eliminated, simplifying design and reducing the BOM cost typically associated with competing in-class MPUs.
