Introduction
data output DRAM devices. Note that the EMC is only available on DSP56724 devices, and is not
available on DSP56725 devices. The EMC includes:
— High performance SDRAM machine
— A general-purpose chip-select machine (GPCM)
— Up to three user-programmable machines (UPMs)
• A seamless hardware Asynchronous Sampling Rate Converter (ASRC) that is accessible to both
cores, to support different sample rate audio data transmission reception. Three data sampling rate
convert pairs can be supported at the same time. Different pairs can be used by different cores at
the same time.
• Inter-Core Communication (ICC) module:
— 32K shared memory between the two DSP56300 cores
— Supports a flexible arbitration system which allows multiple methods of arbitration
— Non-maskable and maskable interrupts between the two cores
— Poll data registers for simple data transfers
• Includes as many as 79 GPIO pins, shared with other peripherals function pins; the actual number
is different for different device packages.
