TMS 9900 has sixteen priority interrupt levels. The Level 0 is exclusive level for reset interrupt. The Level 1 and 2 are for power fail interrupt and real time clock interrupt, respectively. Further, the Level 3 to 5 are used for PTR, TTY etc., which have been connected during the system developing.
The CPU and a microprocessor system
Published in Stuart Anderson, Microprocessor Technology, 2012
One of the first 16-bit microprocessors was the Texas Instruments TMS9900, introduced in 1976. At 32768 words, it had a very limited address range, furthermore, all the working registers were external to the CPU so that execution times were very slow.
Fifty years in home computing, the digital computer and its private use(er)s
Published in International Journal of Parallel, Emergent and Distributed Systems, 2020
Not only gaming consoles but also home computers reached the end of their 8-bit era in the middle of the 1980s. When microprocessor manufacturers (Texas Instruments’s TMS9900, Intel’s 8086, and Motorola’s 68000) started to produce and sell 16-bit CPUs in the second half of the 1970s ten years later those chips got cheap enough to be implemented in home computers and video game consoles.13Apple’s LISA (1983) and Macintosh (1984) computers, Sinclair’s QL (1984) Commodore’s Amiga (1984), and Atari’s ST (1985) started the 16-bit era in home computing. They featured more RAM capacity, faster and bigger peripheral memory and new special chips for sound, graphics and mathematical operations.
