Quad Digital Signal Processor

• Four StarCore™ SC140 DSP extended cores, each with an SC140
   DSP core, 224 Kbyte of internal SRAM M1 memory (1436 Kbyte
   total), 16 way 16 Kbyte instruction cache (ICache), four-entry
   write buffer, external cache support, programmable interrupt
   controller (PIC), local interrupt controller (LIC), and low-power
   Wait and Stop processing modes.
• 475 Kbyte M2 memory for critical data and temporary data
   buffering.
• 4 Kbyte boot ROM.
• M2-accessible multi-core MQBus connecting the M2 memory
   with all four cores, operating at the core frequency, with data bus
   access of up to 128-bit reads and up to 64-bit writes, central
   efficient round-robin arbiter for core access to the bus, and atomic
   operation control of M2 memory access by the cores and the local
   bus.
• Internal PLL configured are reset by configuration signal values.
• 60x-compatible system bus with 64 or 32 bit data and 32-bit
   address bus, support for multi-master designs, four-beat burst
   transfers (eight-beat in 32-bit data mode), port size of 64/32/16/8
   bits controlled by the internal memory controller,.access to
   external memory or peripherals, access by an external host to
   internal resources, slave support with direct access to internal
   resources including M1 and M2 memories, and on-device
   arbitration for up to four master devices (Continue ...)
