MSC8254 Quad Core Digital Signal Processor Reference Manual
A comprehensive reference manual for the NXP MSC8254 quad-core DSP, covering its StarCore SC3850 cores, memory architecture, high-speed interfaces, and peripheral subsystems.
Overview
This reference manual provides technical details for the MSC8254 quad-core digital signal processor based on the StarCore SC3850 architecture. It covers the DSP subsystem including L1 and L2 caches, the Chip-Level Arbitration and Switching System (CLASS), and internal memory (M2, M3). The document describes integrated high-speed interfaces such as Serial RapidIO, PCI Express, and the QUICC Engine for Ethernet connectivity. It also details the dual DDR-SDRAM controllers, DMA units, TDM interfaces, and standard peripherals like UART, I2C, and GPIO. Dedicated sections discuss boot procedures, interrupt handling, and debugging features for wireless infrastructure applications.
