Tachyum은 프로디지 범용 프로세서의 물리 설계에 사용하는 EDA 툴을 새로운 걸로 바꿔, 코어 수를 128개에서 192개로 늘렸다고 발표했습니다. 또 SERDES도 64개에서 96개로 늘었습니다.
L2/L3 캐시는 128MB에서 192MB가 됐고, DDR5 6400에서 7200으로 메모리 지원 스펙도 올랐습니다. 코어 수가 늘어나면서 다이 크기는 500제곱mm에서 600제곱mm가 됐습니다. 그래도 여전히 858제곱mm의 웨이퍼 레티클 제한에 맞출 수 있었다네요.
Tachyum today announced that new EDA tools, utilized during the physical design phase of the Prodigy Universal Processor, have allowed the company to achieve significantly better results with chip specifications than previously anticipated, after the successful change in physical design tools - including an increase in the number of Prodigy cores to 192.
After RTL design coding, Tachyum began work on completing the physical design (the actual placement of transistors and wires) for Prodigy. After the Prodigy design team had to replace IPs, it also had to replace RTL simulation and physical design tools. Armed with a new set of EDA tools, Tachyum was able to optimize settings and options that increased the number of cores by 50 percent, and SERDES from 64 to 96 on each chip. Die size grew minimally, from 500mm2 to 600mm2 to accommodate improved physical capabilities. While Tachyum could add more of its very efficient cores and still fit into the 858mm2 reticle limit, these cores would be memory bandwidth limited, even with 16 DDR5 controllers running in excess of 7200MT/s. Tachyum cores have much higher performance than any other processor cores.
