Texas instruments spice for mac movie#Dalsa, which created the image sensors for the Mars rover Spirit, uses TI DSPs in digital movie cameras. ![]() In video production equipment, the DSPs would allow broadcasters to decompress more streams simultaneously or produce higher-definition images, the company said. This could cut costs and improve energy consumption-a key consideration. (Chips from around 2001 could only handle 16 channels.)Īs a result, cellular equipment makers can insert fewer chips into wireless base stations to handle the same, or a larger, volume of calls, according to TI. One of the new 1GHz DSPs, for instance, can process 55 Global System for Mobile Communications (GSM) cellular network channels at once, whereas an earlier TI DSP running at 600MHz could only handle 35 channels. The processors then try to maximize the number of digital packets a given device can handle at once. Real-world analog data-such as sounds and light-are first converted into digital form by chips known as analog-to-digital converters. Increasing the speed from 720GHz to 1GHz in its industrial line of DSPs improves overall performance by around 40 percent and gives equipment makers greater flexibility, said Ray Simar, TI's manager of advanced DSP architecture.ĭSPs essentially compress data to conserve bandwidth. Texas Instruments plans this week to unveil digital signal processors that run at 1GHz, an advance that will likely help the company maintain its top spot in providing chips for cellular base stations, video production gear and other systems. ![]()
