- A prison film is a film genre concerned with prison life and often prison escape. These films range from acclaimed dramas examining the nature of prisons, such as A Man Escaped, Cool Hand Luke, Midnight Express, Brubaker, Escape from Alcatraz, The Shawshank Redemption, and Kiss of the Spider Woman to actioners like Lock Up and Undisputed, and even comedies satirizing the genre like Stir Crazy, Life, and Let’s Go to Prison. Prison films have been asserted to be “guilty of oversimplifying complex issues, the end result of which is the proliferation of stereotypes”. For example, they are said to perpetuate “a common misperception that most correctional officers are abusive”, and that prisoners are “violent and beyond redemption”.
- The 8085’s register file reverse engineered (righto.com)
On the surface, a microprocessor’s registers seem like simple storage, but not in the 8085 microprocessor. Reverse-engineering the 8085 reveals many interesting tricks that make the registers fast and compact. The picture below shows that the registers and associated control circuitry occupy a large fraction of the chip, so efficiency is important. Each bit is implemented with a surprisingly compact circuit. The instruction set is designed to make register accesses efficient. An indirection trick allows quick register exchanges. Many register operations use the unexpected but efficient data path of going through the ALU.
