Experience power-efficient performance with 100-MIPS ’C549
TI’s TMS320C549 is meeting the need for power efficient performance in the demanding telecommunications market.
Today, TI is shipping 100-MIPS ’C549 samples with full qualification for all speeds (60/80/100 MIPS) planned for 3Q98. In addition to the 100 MIPS of high performance, the ’C549 offers extremely low power dissipation, ultra small packaging, 32K words of on-chip SRAM, and low cost (US $25 for quantities of 10,000 units). All of these features make the ’C549 a powerful choice for manufacturers of high-performance telecommunications end equipment. ’C549 architecture offers efficient MIPSAccording to independent industry reports, the ’C549 has some of the most efficient MIPS of any fixed-point DSP offered in the industry today. 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. The combination of an enhanced Harvard architecture, parallel bus structure, and optimized core empowers a sophisticated instruction set. The set utilizes many single-cycle and parallel instructions. Low dissipation minimizes power consumptionThe ’C549 DSPs dissipate only 0.45 mA/MIPS for their core supply. Therefore, a 100-MIPS ’C549 operating at 2.5 volts would dissipate less than 115 m W using on-chip resources. The ’C549 has three power-down modes: IDLE1, IDLE2, and IDLE3. These three power-down modes 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 mA. Ultra small packaging enables increased density
Greater functionality though 32K on-chip RAMThe ’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. The ’C549 incorporates a host port interface (HPI), a time-division multiplexed (TDM) serial port, a timer, and two buffered serial ports (BSP). Combining two BSPs with the performance and large on-chip memory of the ’C549 allows designers of telecommunications equipment to handle multiple channels with a single DSP. ApplicationsTargeted at manufacturers of high-performance telecommunications end equipment, the ’C549 is an optimum solution for applications like modems, cellular handsets, and dedicated sub-systems. The ’C549 is best at performing a single specific algorithm or small sets of algorithms like those that may be present within modems or cellular phones requiring 50–100 MIPS. These types of applications demand very low power dissipation, are space-conscious, and must be low cost. Examples of applications using the ’C549 include: Wireless Voice Communications
Wireline Voice Communications
Wireless Data Communications
Wireline Data Communications
SummaryThe combination of high performance, low power, small packaging, and low cost of the ’C549 represents yet another example of TI’s commitment and leadership in DSP Solutions. |
