TMS320C6454 Fixed-Point Digital Signal Processor www.ti.com SPRS311A–APRIL 2006–REVISED DECEMBER 2006 The C64x+ DSP core employs eight functional units, two register files, and two data paths. Like the earlier C6000 devices, two of these eight functional units are multipliers or .M units. Each C64x+ .M unit doubles the multiply throughput versus the C64x core by performing four 16-bit x 16-bit multiply-accumulates (MACs) every clock cycle. Thus, eight 16-bit x 16-bit MACs can be executed every c

The boot sequence is started automatically after each power-on reset, warm reset, and system reset. For more details on the initiators of these resets, see Section 7.6, Reset Control

For the PCI host boot, the CPU is out of reset, but it executes an IDLE instruction until a DSP interrupt is generated by the host. The host can generate a DSP interrupt through the PCI peripheral by setting the DSPINT bit in the Back-End Application Interrupt Enable Set Register (PCIBINTSET) and the Status Set Register (PCISTATSET). Note that the HPI host boot is a
