'C549 meets need for power efficiencyTI's TMS320C549 is meeting the need for power-efficient performance in the demanding telecommunications market.
The 'C549 offers 100 MIPs of high performance, extremely low power dissipation, ultra-small packaging, 32K words of on-chip SRAM and low cost. All of these features make it a powerful choice for manufacturers of high-performance telecommunications end equipment.
The combination of an enhanced Harvard architecture, parallel bus structure and optimized core empowers a sophisticated instruction set, which uses many single-cycle and parallel instructions.
The 'C549 DSPs dissipate only 0.45 mA/MIPS for their core supply. Therefore, a 100-MIPS 'C549 operating at 2.5 V would dissipate less than 115 mW using on-chip resources. The 'C549 has three power-down modes -- IDLE1, IDLE2 and IDLE3 -- that enable the power dissipation to be reduced much further than the active power. For instance, in IDLE3 power-down mode the 'C549 has a current draw of less than 1 uA. The 'C549 features 32K words of on-chip RAM and 16K of ROM. This large amount of on-chip memory will enable designers to bring software functions from multiple DSPs together onto a single chip. In addition, the 'C549 can address up to 8M words of code. With such a large address space, the 'C549 can reconfigure itself in operation to run a wide variety of software algorithms available to it off-chip, using an enormous external memory pool.
Targeted at manufacturers of high-performance telecommunications end equipment, the 'C549 is an optimum solution for applications such as voice processing, Internet telephony, modems, wireless voice/data communications and dedicated subsystems. Applications that are power-sensitive, space-constrained, cost-limited and yet performance-driven can take full advantage of the 'C549 benefits.
TI is shipping 100-MIPS 'C549 samples with full qualification for all speeds (66/80/100 MIPS) planned for 3Q98.

According to independent industry reports, the 'C549 has some of the most efficient MIPS of any fixed-point digital signal processor (DSP) offered in the industry. The MIPS efficiency is equivalent to that of a 24-bit DSP, but without the extra cost of interfacing to 24-bit memories. The 'C549 architecture enables other tasks, traditionally handled by ASICs or microcontrollers, to be integrated onto the DSP, thus lowering overall system cost.
