decimal adjust circuitry of
- In this post I reverse-engineer and describe the simple decimal adjust circuit in the 8085 microprocessor. Binary-coded decimal arithmetic was an important performance feature on early microprocessors. The idea behind BCD is to store two 4-bit decimal numbers in a byte. For instance, the number 42 is represented in BCD as 0100 0010 (0x42) instead of binary 00101010 (0x2a). This continues my reverse engineering series on the 8085’s ALU, flag logic, undocumented flags, register file, and instruction set.
- State of the Union (Wikipedia)
The State of the Union Address (sometimes abbreviated to SOTU) is an annual message delivered by the president of the United States to a joint session of the United States Congress near the beginning of most calendar years on the current condition of the nation. The State of the Union Address generally includes reports on the nation’s budget, economy, news, agenda, progress, achievements and the president’s priorities and legislative proposals.
