EXCELLENT PTSC post from Raging Bull: bksd / ALL -- I researched the article you referred me too concerning the Genroco/Ciprico Storage Subsystem. What I found interesting was the ST protocol being utilized for data/video/voice transmission. the protocol is designed to transmit information when "buffer" levels on both ends are met. This reduces the amount of "lost" time/data due to errors in the protocol transmision of data. TCP/IP is prone to send packets of data across networks in multiple levels of data bundels. Specifically, the PSC1000 Microprocessor is designed to increase performance and lower cost of program execution. The PSC1000 beats out the competition because they are able to achieve their results by REDUCING the number of operand bits. Now, that is important because by eliminating redundant bits in the instructions. This is EXTREMEMLY BENEFICIAL for performance by the decreasing the program size. And, it allows for a greater bandwidth size. Remember when I told you about why bandwidth is so important? The convergence of voice/video/data across digital networks NEED a way to increase bandwidth capacity over exisiting infrastructures. Ok .. so this is accomplished in 1 of 2 ways -- You can build networks which have the capability to increase bandwidth size or you can find a way to transmit information in a more efficient format. Companies i.e. Lucent have gone the former route. Lucent recently purchased Nexabit for the sole reason of having a solution of increasing network bandwidth capacity by a design which is optimal for voice/video/data transmission. TellLabs, as of tpday 7/1, purcahsed a company as well which has designed a solution to the same. The other alternative would be to find a more efficient way of transmitting voice/video/data utilzing the exisiting network infrastrucutre. Hence, the PSC1000 chip. Now , Ciprico stated that "high speed storage is important to many of Ciprico's Geospatial Imaging customers." The high speed storage solution they have developed here will save "...time and money with fiel storage and retrieval...". So ... why would Imaging companies benefit here? Companies which utilize imaging on the Inet transmit files around with LARGE BYTE SIZES. They also execute on Image files with LARGE BYTE SIZES. See the connection? Patriot has a chip which REDUCES the size of programs and files by ELIMINATING redundant bits. Thus, you have a SMALLER stack size of instructions. Now, the JVM implementation which Patriot has developed for the PSC1000 is beneficial because Java is designed to run on a STACK ORIENATED ARCHITECTURE. Thus, the PSC1000 REDUCES BYTES, OPTIMIZES INSTRUCTION SETS, AND EXECUTES MORE JAVA BYTE CODES IN 1 INSTRUCTION SET PER CLOCK CYCLE! - J
