i'd always prefer cash to cache

So u don't know what a cache is... a cache is a high speed memory lying between the CPU and the RAM which is used to speed up the execution of the processor... and I was trying to figure out how to use a computer simulation program to find out the optimum cache parameters...

Basically there is a software called simplescalar see here, which is used by most research groups to simulate computer architechture... but the problem with it is that it simulates the whole program for every small change in parameters... i was trying to comprehend its source code to find out a means of removing this problem... and make the cpu execute only the instructions that are of interest to me... in terms of the CPU module i want to examine... whatever be the case, it s a tough ask from anyone... the source code is over 20 different files... and i went mad just trying to figure out which file contains which function...

then apart from that the day was pretty peaceful... nothing much to do... went to have dinner at Billoos... a thing worth noticing is that whenever there is a super special in out mess... food one day before and one day after is really bullshit   they king of average out the food quality... anyways, since i was already suffering from loose motions... and was really hungry, i decided to have some dal and rice at billoos... just to satisfy my hunger....

nothing much to write... i finally figured out what DMA is...

and tommorow i again start the great battle with the 4-bit CPU i am designing... for some of its characteristics read Gaurav Sahni's blog... he's explained it pretty well and so i will not waste time on trying to do the same...

whatever be the case... last 2 weeks have been completely taken up by the CPU and i really wish that we finish it...

bbye and good night
